ATI MOBILITY RADEON HD 2600 graphics with 512MB GDDR3

x360progamer, I found the solution to get rmclock to run. It's posted here

I'm searching, but can anyone tell me what the ideal voltages would be for me to use for undervolting on this laptop?

 

Seems like too much trouble to go through... Plus I have no idea how to overclock the GPU or undervolt the CPU so I don't think I'm gonna take the risk... I read the "how to overclock ATI" or whatever but almost everything they say has me confused...

 

dph: EVERYTHING I have tried has worked it hasn't crashed on ANY voltage yet, using both Orthos and HotCPU to crank up the CPU usage...

I set it at 1.000v for the highest "index" and let it auto-calculate down from there for the other indexes... using 1.000v or .9500v, you should get cool and power-stingy! Right now, I'm on .9500v, 85% battery left, and it says 2:23 remaining, LCD set to 3/8, WiFi on, surfing around. CPU core temps are at 28c/26c (Core0/Core1) GPU at 42c

T

 

I've got it set to 1.000v for the upper limit and othos is going well for me (so far 15 minutes and counting. Going one notch lower crashed Orthos after 15 seconds, but this voltage seems quite stable. Temps are at 61c steady with it at 100%.

What did you use for "auto adjust", the "auto adjust states VID" checkbox?

 

Yep - that's the checkbox.
It just backfills from your setting on index 5, to index 1.

Right now, I'm on battery, running "Power Saving" profile, .9500v, locked to 6x multiplier.

I have no clue how to overclock or undervolt, I read all the guides but I still don't get it so it is pointless, but I should be running smoother anyway with out overclocking.

Here is a video I made, me playing Crysis Demo, the sound is a bit off because FRAPS sometimes does that, and I know I suck at the game lol.

All settings MEDIUM, resolution 1280x800, AA off.

The most frame rate I got during this video was 12...

Are my drivers out of date?

 

YES I DID IT!!! I just overclocked my GPU and it went from my previous 3,602 to 4,050! My temps got a bit hot, it was like 71C

 

Congratulations! What clocks?

 

Shark, it didn't backfill the voltages for me, not sure why. I just filled in values between the lowest and 1.0, but can you tell me what it set yours to?

Congrats on the OC x360, I plan to OC the video too when I get home from work tonight. Hope mine does as well as yours.

 

My 3DMark06 Score went from my previous 3,602 to 4,050 to 4,240.

My temperatures seem good right now but we will see.

I still struggle a bit playing Crysis on full MEDIUM but it is playable now

Right now my clocks are set at 621 ENGINE and 729 MEMORY, this is AMD GPU Clock Tool so I guess it would be the equivalent of saying 621/729. I'm still messing with it though!

 

I had trouble getting some of the programs to install yesterday to perform the OC. Which ones did you use to OC the video card X360?

 

I used AMD GPU Clock Tool. I can run Crysis on everything MEDIUM including a few things on HIGH

 

Is the 2600 better or worse then the newer Radeon 3450? I know the 3450 is kinda a more low-level card, but wasnt sure if it was any better due to being newer. Anyone know?

 

The HD2600 is better without a doubt. The HD3650 (55nm) is a die shrink of the HD2600(65nm), so its only better by clock speed.

 

I don't think it's just a die-shrink - The HD2600 is model M76M, and the HD3650 is the M86. Codenames are HD2600-RV630, HD3650 RV635.
The HD2600 supports DX10 and DDR2/DDR3. The HD3650 supports DX10.1 and DDR2/DDR3/DDR4.
Also, the HD2600 has a PCIe x16 interface, and the HD3650 supposedly a PCIe x16 2.0 interface.

I think it's gotta be at least a LITTLE more than a die-shrink to add DX10.1, DDR4 capability, and PCIe 2.0 support.

Now - what all that relates to in performance increase, is ANOTHER question altogether

@Slayer: As Johnny T says, 2600 is superior. 3450 is 64-bit interface, M82/RV620 GPU. 2600 is M76M/RV630, 128-bit interface.

@dph1077: when you click on "Profiles," and select your profiles for plugged-in and battery, make sure the backfill is checked on, click "Defaul Values" then drop the voltage list on the last down on the list, select 1.000v, and it will reset the others. When you click "Default Values," it SHOULD reset the bottom one to 1.250v, and as you go up to index 4/3/2 they will get lower.
Once you select 1.000v in the bottom of the list, they should go lower as you go up, but starting at 1.000v might have, for example, index 2 and 3 be both a .9750v, as there's not (5) intermediate voltages.

X360: Undervolting will lower your GPU temps, because the CPU heat is less, and they share a heatsink/heat-pipe assembly. You SHOULD be able to push to 621/748 like I was, but that's probably edge-of-the-envelope. When I was goofing around for longer than 3DMark06, I ran it at 600/728 (+/- a couple mHz on the mem clock)

Let me know if you need more info.

hmmm im using the amd gpu clock tool and my temp is 65 degree average without playing a game and goes up to 80 in a game, and that is at the default engine and memory clock speed which is at 297/405....when i overclocked it to the same as x's i was getting temps of 78 out of game and 90ish in game....pretty sure thats not good. how to i undervolt to lower the temp of my gpu?

also i have a double fan that i use to set my laptop on yet my comp is still really hot...

 

Get a laptop cooling pad that will help, then undervolt, I have no idea how to so I'm not going to risk it, plus RMCLock doesn't work for me...

 

so the cooling pad would work better then the double fan that i have my laptop sitting on?

and also when i overclock should i be noticing significant fps change?

 

X360: Undervolting I can;t see as risky - OVERvolting, maybe. It would just be unstable, and not work right. X, what are your DEFAULT core/mem clocks?

Timd: Mine, standard clocking/standard voltages, was about 70-72c for CPU, about 73c for GPU. Overclocked, I get in the 60'sc for CPU, and 68-70c for GPU

Timd, you're saying your DEFAULT clocks are 297/405? Which laptop do you have? Strange - on my M-6851, they're FACTORY at 500/600 (technically, 499/598 I think)

Download GPU-Z from here and see what it says near the bottom of the main screen.


EDIT: Dang - Fay is starting to whip up some palm trees here, and looking out the window, i can;t see the freeway, which is about 125-150ft away!
EDIT 2: I'll be danged, if it doesn;t look like it changed direction!


T

 

when i use that gpu-z program it says what you said (499/598) but in amd gpu clock tool it says 297/405

x what does yours say in amd gpu clock? what should i use to overclock my card and what do i use to undervolt?

also, i have the exact laptop as x, the m-6864fx

 

@x360, you can find how to use rmclock here, the link for the 64 bit fix is towards the bottom of the tutorial.

Hmm, not sure what I'm doing wrong, but I am not getting those good scores on 3dmark06, only 3662 after undervolting the cpu and OCing the video card to 600/720.

 

hey im trying to undervolt but i just want to make sure that the default voltage is 1.2500, and you can only lower it .0125 at a time. also do i undervolt only the 12x one or all of them?

also what were you able to lower it to? how much cooler did it make your cpu?

what did u use to overclock the video card?

 

Tim, the link in my last post shows perfect instructions for undervolting.

You can move it more than just .0125 at a time, but it's not advisable. It's easier to do it one or two steps at a time to make it easier to find the stable voltage.

 

for me, i can only adjust the voltage right now by .0125. also do i only adjust the 12x one? what was your stable voltage? i have the EXACT same computer as you so cant i use the same voltage as you?....also did u undervolt both cpus?

 

I am going to assume that doing it for one cpu does it for both as I don't see anything in the setup that says it's for either one.

What I did was change the last entry 12x by 2 steps each time until it got to 1.00v and ran Orthos stable at that rate. Your pc 'should' use the same voltages, but nothing is 100% certain, it's best to take it slow just in case. I ran Orthos for about 20 min at each cycle until it failed at .9875 for the 12x, then bumped it back to 1.000 and ran it as I stated.

Hope that helps.

I'd still like to know how others managed over 4k on 3dmark06 LOL

 

thank u, i will try that

what did u use to overclock? amd gpu clock tool?

i would also like to know how x got 4k on 3dmarks and how he got 70 temp after overclocking without undervolting..

what temp are u running at 1.00v?

 

Yes, I used AMD GPU Clock for OCing the video. I currently have it running at 614.25 for the engine and 720 for the memory clock (scored 3702 3dmark06).

When I use Orthos to pin the system at 100% with the 1.00v setting it gets to around 62C.

 

Also, make sure you are using the latest version - I am using v0.7 of AMD GPU CLock Tool.

FOr laughs and grins, what BIOS version are you using?
On power-up, press [F2] and you'll see it on the main screen.


T

 

I am running bios 91.24

I'm not sure which version of gpu clock tool I'm using, it's either .7 or .9.8

 

did you ever figure out why it's showing 297/405 using the "AMD GPU Clock Tool"? I just downloaded it and am also showing the same numbers

 

Hmmm... AMD GPU Clock Tool shows 499.50/594.00 on mine.

Clicking the "Get Clock Info" button, gives the same: 499.50/594.00

yo x....are you still looking for a config for the hd 2600...Ive been trying to make one that averages 30fps...i got a new one for u if u want...also...what do u get for framterate on low and on medium...i seem to get like 40 and 20...the best i could do was 30fps with hdr and shadows...the next was one with hdr.sun shafts.coronas ...high detail shading...and avg 25fps no overclocking...i dont think its possible to make a config that looks high and averages 30fps...just aint gonna happen...but 25fps is pretty close.

on the benchmarks it will say avg 22fps..but when i play the game i get like 15-23 fps...so im assuming the 25 fps avg will play like 20...and the 30 fps avg like 20-27 fps...

if you are happy with medium settings and just want more fps...i could make one.. anyone else wanna help make a config for hd2600 and 8600m gt level cards>????

 

btw to all you guys overclocking...

overclocking a laptop gpu is pretty dumb...the excess heat will slow down your cpu in the mid term(couple months)..and the gpu will burn out much sooner..i used to over clock alot and i ruined a few computers doing so...even small overclocks of 50 mhz used for a couple months is very harmful..heck just having normal clocks at 100percent too often isnt good...just like if u over play on video game console..it will heat up and burn out very quickly...i burnt out my dreamcast for overplaying it...same for my xbox....


also something to think about...overclocking my gpu to 640/740 will add only 4 fps to the game...but after about 3 or 4 min it heats up too much...display driver goes down and the framerates crash...and since ive been overclocking the avg framerates when not overclocking have gone down slightly because of the heat damage...

i use gpu tool and 8.8 drivers...but just thought id give u guys the heads up i have the same computer and its damaging the gpu and cpu....my cpu mark score is cut in half...was at 8500 now it gets 4500 no matter what i change...so yea...dont make the same mistake i did...and if yours isnt wreaked be careful overclocking past 50mhz for more than 30min

 

Actually no, the HD2600 GDDR3 is essentially an unclocked HD2600XT, so it is designed to run at much higher clocks but is limited by its voltage. I OC'd my GPU to 620/720 and I got a 20FPS boost in CSS. Never over heated. HD2600XT clocks are 600/700 by the way.

 

yo T...where and who says the mobility hd2600 is just a underclocked hd2600xt.
And how can you say yours doesnt overheat..if i overclock mine it goes up to 78c outside...unlesss i was playing a game in a walk in freezer...my temps go way up...and i have the exact same card.. maybe you have a super card, or maybe u undervolted your cpu..


thats cool about your ectra 20 fps...butwhen the avg is at 160..your eyes wont notice the extra 20...so its a waste..

any demanding game like crysis cod4 bioshock ect that averages 20 fps max oc will only add like 4 fps..small increase for shortening the lifespan of your card...better off lowering your rez or some settings via a config

try usings caseys config for ccs see if u dont get an extra 90 fps...alot better than overclocking...
crysis config i have for medium gets 34 fps vs 20 fps...try overclocking till medium hits 30
my config for crysis high gets 25 fps and has some very high settings added plus very high shading...gets 25
if i tried getting 25fps avg with shaders high and shadows med everything else low...id have to over clock to about 900 mhz core.

configs are intelligent...overclocking is moronic..unless u have liquid cooling and a desktop graphics card and dont exceed 70c

thats all i could find... the stock clcok core for the xt is 700....good luck playing at 700 core without any problems for more than 1 min....haha...and then again it can be overclocked more so than the hd2600...i hearda 880 core..stable..without overheating... imagine that...a hd2600 overclcoked to 880 stable...unlikely unless of course you were just attacking my good point without proof

 

also..

what drivers do you use, and do you have a config for crysis...im trying to make one but its not easy to get framerates higher than 20 with settings looking high/veryhigh i can only get 25 avg...have u had any luck finding a good config for crysis.

 

Faster clocks is all that 'XT' has really ever signified in ATI's product line....

The 2600XT is just a faster 2600 - faster clocks, same core..

Hmm....reminds me of "Tastes Great, Less Filling"


Ryane: You're running your CORE at 700? Mine fizzles out past 621...
I can do near 700 on mem clock, but anything over, and I get artifacting.


T

 

lol no dude im not running at 700 core...thats not a good idea for sure

i posted the hd2600xt specs then the hd 2600 specs look closely at the core speeds..i was responding to T's response about the hd2600 just being a underclocked xt...that just isnt true...heck your comment about artifacting past 700 supports my claim...it it was underclocked like the hp 8510p(400 core) then yea its safe to have 500 core...same goes for the xt vs normal hd2600
if the hd2600 was underclocked the same way the hp 8510p was then yea 700 would be safe...but u cant even over clock it past 650 safely...so hes just wrong or confused with his comment to me..


I think T is a rookie when it comes to laptops or something..maybe we can help him learn a bit more..the same goes for me...knowledge never hurt anyone

 

The info you provided above show that the HD2600 and the XT have exact same specs just different clocks, understand that? They are they same physically but has different clock speeds? I can say mine doesnt over heat because it hasnt down clocked automatically. Maybe my notebook just has a good cooling system. and yes I have undervolted my CPU.

 

i figured out what was giving me the weird numbers. i had to disable "PowerPlay" in the Catalyst Control Center

 

isnt powerplay supposed to be...good?

 

When you notebook is on battery yes.

 

so what's up with this? i disable powerplay and my GPU settings now show what it should be on GPU Clock (499.50/594.00). I play a couple of games and it runs alot smoother.

i tried enabling Powerplay again while i have my power option set at High Performance and Maximum Performance (Plugged In) in the powerplay settings. but for whatever reason as long as I have powerplay enabled my GPU settings always reads 297/405 instead of of where it should be by default 499.50/594.00?!?!

so should i keep powerplay disabled. i do want the feature to have the GPU run at a lower speed when I'm on battery power but it seems that even if im using "plugged in" power and as long as powerplay is enabled imy gpu doesnt use the default settings.

weird

 

Just enable it when you use your notebook's battery, thats what I do.

 

Ryane: The 2600XT is a HIGHER clocked RV630 GPU, not an OVERCLOCKED 2600.

Semantics, yes - but that's what it is. Maybe it's like what they do with CPU's: cherry pick the best that will run at the higher speed, and use 'em as 2600XT. WOuldn't be the first time. RAM was originally sold that way.

If DRAM chips failed at 80ns, they battery-test at 100ns. If it failed at 100ns, test at 120ns. if it works at 100ns tested, mark it as -10, and sell it. If it fails at 100ns, but works at 120ns, mark it as -12, and sell it.

Was the same in the 80's, same in the 90's, and probably the same today.
They obviously want to make as many 2600XT's as they can, as those sell for more. THose that fail at 2600XT specs (700/750) get tested at 2600 speeds (500/600) and if they pass, get marked as 2600 parts.

Simple, really, and all comes down to yield - get as much product out of your manufacturing capacity as possible.



T

 

the 2600XT gets more volts for higher clocks.

 

I tried to download the 64 bit driver for RMClock but it won't let me open sys file!?

Also when ever I restart my laptop any overclock settings I used revert back to some random one in between the stock settings and mine...

Any ideas!?

 

interesting..i love my hd 2600 but the hd2600 xt seems to be alot better..kinda like the diff between the 8600m gs and the 8600m gt..

also i heard alot of talk around here about the hd2600 vs the 8600mgt people seem to say 8600mgt gddr3 >hd2600gddr3>gt ddr2>hd ddr2

but no one posts results for the 8600m gt gddr3 that are stock results.
it gets 3100-3800 3d marks stock on average...and my hd gets the same results...how does a nvidia card that gets the same results get a higher rating by people..i dont get it

my windows index rating for graphics is 5.5...and a week ago i went to futureshop and seen a 9600m gt with a index of 5.4...also my 3dmark 05 of 8500 seems to be way beyond most gddr3 gts on the futuremark site..only ones i seen that were close was extremly overclocked and the others were sli...


ill check for a stockgddr3 in both versions and use 3dmark 05 because i heard in a nvidia forum the drivers are tweaked for the program 3dmark(figures why games play better on the hd2600)
