OC'ing my 5870m

Well i used to use msi afterburner to OC my old 4670, and it worked fine. I downloaded msi to OC my 5870, and the core and memory clocks are already right at the top of the bars, at 700/1000. How am i supposed to OC this lol?

 

Evening Mr Turner,

I wouldn't use MSI for your ATI you have a built in overclocking facility in CCC under the performance section. I seem to remember when we spoke you have the latest Vbios so the overdrive option should be unlocked just click the key to unlock the clock bars and it comes with a handy tool to test for artifacts.

Stress test using Furmark to find your highest overclock. I have a movie in my sig which covers the basics if you need any more assistance.

 

hmm i have the 11.8 preview drivers, and there is no performance section, and no facility to overclock. ( that i can find anyway )That is why i downloaded afterburner lol. I really dont like changing drivers, as it bricked my old video card.

 

What drivers did you install the preview drivers on top of?

Can you post a screenshot of your GPU-z need to check if you have the latest Vbios because you will need it to overclock. It is very straight forward to flash the vbios actually much more than the system Bios I have found and I have flashed mine several times and only missed a few heartbeats as its a quick flash

 

May I suggest the AMD GPU Clock Tool to overclock your GPU?

Download AMD GPU Clock Tool v0.9.26.0 For HD 5870 | techPowerUp

Be gentle

 

Has the problem with the voltage been fixed with the JH though? I find when I overlock with AMD GPU clock tool it keeps my voltage at 1.15v and I have the latest Vbios. I think the OP's problem might be that he is on the old Vbios which causes issues when you try to overclock and does not have the overdrive option....but the OP seems to be too busy gaming to respond

 

It means you may have the latest vBios, but the vBios modified to unlock OD. This can be done easily by using Radeon Bios Editor. Just go to the last tab and keep moving the sliders for the core and memory, save. Reload and move the sliders over again until you get the desired speeds.

This will unlock OD, flash to your modified vBios and you should see OverDrive in CCC.

Also I find Afterburner from MSI works better for Nvidia and think it was designed more for them. Sapphire has Trixx which works better with AMD. If you don't want to mess with vBios, then just use Sapphire Trixx.

Also drivers won't brick your GPU, that's just hogwash. Unless it's an Nvidia fiasco that doesn't have any limits causing the GPU to overheat. Changing drivers on AMD will do no damage to your card. If it happened on AMD before, then it was a user error, not the driver. Don't blame for something that was your fault, that's just immature.

 

If the OP has the latest Vbios there is no need to flash the Vbios again with modified clocks and risk a brick when you can just use a facility to change your clocks anyway and this can be set when you enter windows. If he does not have the latest Vbios then it can be got from Chastity's Driver Reference and Application and this also has the battery saving Vbios OD2 as well.

I would not recommend using RBE to the OP personally unless you know exactly what you are doing with it.

Everyone to their own when it comes to overclocking but overdrive is the easiest way to overclock an ATI card for someone that is new to it.

 

You can eighter set the voltage to 1.15v or 0.95v. Those are the only voltages you can select since the card has been hard-modded in the g73jh. I personally like the amd clock tool since when u're done gaming, you can just select 'restore default clocks', and with the chastity vbios, that brings em down to 400/700 (or somethin). I personally got to 850/1300 ^^

 

Stable? Do you have any benchmark results from that?

Was that only through GPU Clock tool specifically?

Very Interesting........'Scratchs chin and considers the possibility of higher clocks'.....

 

Ill bring up my benchies specially for you ! which ones do you want ?

 

The highest you got and as much info as you can give me about how you got to them!

I noticed minimal if any changes from using different facilities to overclock with are these clocks specific to GPU clock tool or in general you are able to clock that high? I have not actually used GPU clock tool to test with so at the moment my hopes are high if this is the case!

 

Sorry for not replying lol. Here is my GPUz

Thanks!!

 

Oh fiddles, I didnt make it home last night, I crashed with my girlfriend.
Ill try and make it home tonight though and get you those numbers !

 

More info please

I am curious as to what modifications you made to the heatsink, pads, paste etc to reach those clocks if any? or was your chip just able to reach those clocks stable from stock?

Can you only get them by using AMD Gpu clock? Or in overdrive as well. Do you have any artifacts?

 

Not modded at all! The only thing I did was a repaste with IC-7. Guess I'm one of the lucky ones ^^. I got artifacts as soon as I went above 870/1300 though.
Benchies for later

 

Disgraceful overclock on the memory that is lol Your Bandwidth must be pushing 80-90Gb/s

Yeah please be interesting to see your benches!

 

I don't know which benchmarks you wanne see though.. I got the 3dmark vantage and the 3dmark06, anythin else you want me to run with that? Any programs I might wanne use ? Im a benchie-noob ^^.

 

Anything you have mate just wouldn't mind seeing the results you got to compare the GPU scores against.

A screenshot of your GPU-z would be most intriging

With those GPU clocks you really should consider a 920XM because you would destroy all other Asus G Series easily 17k+ on 3DMark06 etc

 

A question off topic, is there a big difference between the 940xm and the 920xm? Or how about the 2nd gen Intels like the 2720qm ? I know there are posts on the forum, but 'me so sleepy right now'

 

940XM is the max for our JH, Gen 2 do not fit if that is what you meant if you mean in tems of power an unlocked 920XM is no different to an unlocked 940XM they both can hit 4.0Ghz max and the multipliers can be selected exactly the same which is why the 920XM QS models are such a good deal because the 940XM are still quite pricey.

The only difference is when they are locked because the 920XM varies from 2.0ghz - 3.2ghz the 940XM 2.13ghz - 3.33ghz but you would not be buying an XM to keep it locked You want all 4 of those bad boy cores running a full pelt not downclocking like the QM models.

My 920XM with my clocks (sig) Core1: 3.8ghz Core2: 3.6ghz core 3+4: 3.2ghz benches on par with a 2620QM and when overclocked to its max with twin turbo active pushing 4ghz it hits the same benchmark score as the 2720QM, but does require extra cooling and is as stable as a 2 legged goat.

In other words they are very much a worthy upgrade.

 

I got an appetizer, since I forgot I don't have 3dmark anymore , I'll install it as soon as I get back home to my external hdd.
Here's my gpu'z, while playin 30 mins of BF BC2. I know it aint 850, but i'll get there .

 

LOL Bandwidth for a 5870M

 

Since we're on this topic again, do you gentlemen find the 800/1100 (or higher overclock) beneficial IN-GAME and not just on benchmark scores? I find the 15% overclock definitely does not translate to a 15% performance increase in gaming. Thoughts?

 

This is always the case with overclocking though because the 5870M bandwidth is already enough to produce the results with the settings it has at stock 64gb/s still beats GPU's around at the moment so you wont necessary see a 15% increase unless it can utilise it.

But the old saying goes every little counts and in intensive games if the extra 4-5fps you gain from overclocking keep things smooth its beneficial to overclock. I use 840/1135 when benching 825/1125 when intense gaming but I find 800/1100 is a sweet spot for me.

 

Well where I get 37fps with 700/1000 in one specific level on a specific point, I get 44fps with 800/1300. These are not that accurate, I know, cause there's always the movement/smoke that makes a difference. Thats why I ran a Dirt 3 benchmark:

700/1000:

total frames:3217
average fps: 34.13
minimum fps: 27.31

800/1300:

total frames:3941 (+22%)
average fps: 37.93 (+11%)
minimum fps: 30.70 (+12%)

It depends on how the game is coded though. I get a better increase in BFBC2 .

 

Pardon me for laughing that you a comparing a near 33% overclock on the memory in a notebook with stock cooling! hahaha. People have been calling a few of us jealous of the G74 but god damn I am jealous of your 5870m. When you sell it let me know please.

 

Lol whats there to be jealous about ? Everyone knows ATI kicks Nvidia's

Yea its amazing that I can clock to 1300. I wonder though, how far can I really go ? Is there any danger to it? I guess I'll probably just get some artifacts as soon as I push it to high. More benchies are on its way

 

soooooooooo, did you look at my gpuz???

 

You should be hitting Artifacts already god knows how but you just must have some anti reject memory controllers pumping away or the voltage is somehow now 1.15v lol never seen above 1200 on the 5870M not stable at least.

Yup your Vbios is out of date and needs to be flashed to be able to use Overdrive and prevent the GSOD issue.

V93 Vbios link

Instructions and movie of exactly what to do in order to flash it.

Compliments to Chastity and Brian at Asus.

 

ah i cant be arsed messing with it. I might have a go, but, i dont know.

Thanks again!!

 

It is very simple and very straight forward and yes you are right to be scared of flashing I was and am and always will be because being without my laptop is being without an arm or a leg. But you have to be very unlucky to get a bad flash and normally power failure is the cause but the Vbios is so fast you would need to be hated by god for that to happen.

However,

It is a vital update that could prevent GSOD problems and also allows you to overclock with Overdrive, the information and video in the post I gave you is very easy to do.

You literally create a boot disc using a USB flash drive
Drag the files onto it
Restart and hit esc and select the flash drive
Type DIR to find file required to flash either Atiflash or Od2 and type it.

The rest it does for you within seconds you restart and bing bong done.

Read the instruction watch the movie and follow it exactly and your sorted.

 

Here's my Gpu-z with an 850/1300 OC:



The Vantage Score:


The Vantage Settings:


And finally the 3dmark06 score (with standard Cpu clocks, since I'm a total noob in OC'ing my cpu ):


I tried the 850/1300 OC for the 3dmark06, but it crashed . So I had to settle for 800x1300.

 

Dallers.. Promiss me you won't get jealous..

I've OC'd to 850x1350 and run Vantage again:




Strange that 3dmark06 won't let me use 850 coreclock ... Ill try lowering my memoryclock and see what it gives.

 

+1 for taking the time to do the benches.

You really need to get a 920XM in there and then test it because I can hit 10800 currently in Vantage but should be able to reach 11000 with my 920XM and only 835/1135 the 920 practically doubles your CPU score to 20000

So you would probably see around 11500+

 

Its no problem at all, I've wanted to run those for some time ^^.

Maybe I'll go for the 920XM, I just gotta get more info about the whole oc'in the CPU.

One more thing though, after I OC'd to 850/1350 and returned to the standard clocks I just watched an episode of Breaking Bad. Almost at the end my laptop froze on me. A hard reboot was required. Couldn't do anything. And the 3 times after that. So I unplugged, and ran in battery mode. Havent had problems with freezing the last hour or so. What might have gone wrong? Possibility of damage ?

 

I'd hope not but those are insane clocks to bench at. I'm benching today and the best I can run is 800/1020 without artifacting and crashing Vantage. I hit a 10059 best and that is with a 920xm, you toasted that with a 720qm.

 

All the info you need is in my sig if you can put up with a cockney accent I explain exactly how to overclock your CPU correctly. Locking up and freezing you will need to get used to because its common when finding your highest overclock and BSOD are common when overclocking your CPU but after a restart you just try again.

I am honestly not suprised you locked up with the memory set at 1350 I cannot believe that is stable at all and its very suprising that you dont artifact you must just have some very well binned memory controllers right there even so if 1300 is stable for you then stick with it.

My 920XM thread in my sig also explains what you can expect from it but have a go with SetFSB first and see what your 720QM can produce, applying the win7 timing fix is also beneficial. All explained in my vid.

Have you repasted yet? Might be an idea to see if you can push those memory clocks up a bit could be your memory controller on the chip is not conducting with the heatsink properly because you should have a bit more overclocking ability that 20mhz.

I just conducted a total repaste, pads the lot going to begin benchmarking as my CPU temps have dropped marginally and hoping I can get my XM upto 20k in vantage now.

 

My CPU and GPU temps are good. My GPU at 800 core runs 75c furmark after 10minutes with a 68f room temp. I never replaced my mem thermal pads <-- That is likely my problem.

I was running 1050 a bit but I kept getting memory related artifacts and I eventually downclocked my mem to 1020 where it stopped.


So I said screw it. Ordered Fujipoly 0.5mm thermal pad sheet from FrozenCPU. Looked up a discount code pcapex for 5% off and did 2-3 day shipping. Lets see if that'll help next week

 

Thats like it! Never give up overclocking . I think I'll repaste my GPU soon as well. I never did patch the RAM memory though. Anyways good luck with yours !

 

It might it might not but if it is going to make a difference it will be the clearance from the chip to the heatsink the Vram does not effect the ability to overclock the memory it is the controller located at the edge of the core so if the heatsink is not making contact that can cause problems.

I found with 0.5mm my heatsink sits properly and flush over the core before the stock pads pushed it up at an angle and it was hitting 105oC, 70oC max for me now

 

If your temps are below 95C, then your memory issues are not likely to be thermal related.

You're just stuck with whatever OC you can get. That's all there is to it.

 

Well, its a sheet so that I will cut what I need then have extra for the future. So even if it doesn't help, 20 dollars still well spent.

And since I'll be doing a teardown, it'll be a good time to upgrade my ram for VM's and try to get my touchpad to work again.

 

ok ive started to get lots of the vertical lines and lock ups (GSOD's), so ive decided to do the VBIOS update. Wish me luck!!

 

^^ Good luck! And to be honest, Ive flashed mine a good 30 or more times lol you'll be fine

Daverish: Those are the same pads I have lol it has helped my temps with ICD7; though I have one of the earlier revision 5870's so I still max at about 84 stock, and 89 OC'ed

 

good good. Btw, it is "delete" to get into the BIOS isent it? I've never been there

 

Well if you want to boot straight into the USB stick, use the ESC key instead, which brings up the boot menu, then just select the USB

 

oh ok thanks, see you on the other side!!!!!!
