BIOS modding for GPU OC fun and profit!!

It is possible that the clock tool is preventing the BIOS from throttling the GPU like it should, though this is the first I've heard of such a thing happening. Also, try dusting out your heatsink/fan with canned air. It's possible it has gotten clogged up with dust.

If you're still into testing, try following the methodology here and let me know the results: http://forum.notebookreview.com/gam...-how-overclock-ati-5650-a-13.html#post6801987

 

Cool, thanks. I will give it a shot. Otherwise, it is probably good enough (or as good as it will get). It is amazing the difference between 800/900 and 800/1000. Too bad my system doesn't seem to want to handle it but maybe if I clean out the fan, etc. (and remove the dust filter), it will work or something close to it. The air intake location on these things is terrible if you ask me (ie, when the monitor is up, it gets covered) which I think has a huge negative overall impact on cooling the system.

 

Seeker,
Hey again, I am no longer going for more OC'ing speed because I came across another issue. The issue that I am having now is that when the 800/900 modded A12 bios fluctuates between 300 to 800 on the core and from 796.5 to 900 on the memory, I get lines flashing across the screen at times or quick shifting of the screen. The temperature seems to be fine (lower 70's at the most) and don't see any other issues but I do see lots of fluctuations when I am watching videos, but seems to stay right at 800/900 when gaming or stress testing and have not noticed any lines or screen shifts when the clock speeds are constant. I did not have these before the OC BIOS. Any idea as to what could be causing this? Is the overclocking too high or is there another issue (ie, BIOS setting, throttling, etc.) that is causing this? Thanks again.

 

Follow Up - the above screen disturbances appear to only be on my external monitor hooked up via displayport and not on my laptop monitor. Thanks again.

 

Hello seeker.
Can you to core800 and memory900 bios for my xps1645 4670HD? Its seems stabel with furmark and games..

 

He read your mind^

 

thanks

 

its downclocking littlebit when temp reached to 84, what about A09 and A12 mix with these clocks??

 

Yeah, the same thing happens to me. I am not sure but I think this is the A09/A12. I think there are different types of throttling-temperature and power (and maybe others?). I am not sure though. Seeker?

 

I don't remember if it was a A12/A09 mix or not. I'll re-make it so you'll know for sure.

 

Please forgive me if this has been gone over, but I needed piece of mind before I tried flashing! I currently have a 1645/i820/4670 and wanted to apply one of these updates. I currently have the A09 bios, so would using the 1645_A12_4670_800_900 be my best bet? Do I need to downflash to any bios before I apply these if I'm currently at A09? Thanks very much!

 

Here is A12 ACPI tabels for 1645: http://symmi.planet.ee/stuff/Failid/AcpiTbls.rar

 

Hey seeker can u disable hpet in bios??

 

I'm sure it could be done, but I don't know how. I haven't really messed with anything outside of the vBIOS. I just need the ACPI tables because the tool I use to unpack / repack the BIOS won't function without them.

 

Hey Seeker, sorry to bother you, but did you happen to glance at my question above as well?

 

All 3 of you should try this one: 1645_A12_4670_800_900_A09vBIOS.zip

 

Thanks a ton Seeker! I'll have to make sure I have the correct bios to revert it just in case as well.

 

No problem, just grab a copy of the stock A09 off the Dell website.

 

It worked fantastically! I wasn't expecting much of a boost, but it's quite noticeable, and it barely did anything to my temps! Thanks again Seeker!

 

Excellent, I think I was getting the flickers on my external monitor due to the throttling. The temperatures are much more stable than with the other A12 800/900. Now mine stays in the upper 70s with Furmark (with all the bells and whistles going at 1900x1080-Xtreme Burning, Displacement Mapping, and post fx) whereas the last one would spike up to mid-80s and drop back down to 70 or so and up and down and Furmark would almost appear to freeze at times and go down to like 1-2fps but now it stays steady at 6-8fps. Thanks so much, Seeker!!! You are the man!

 

Glad it worked for you. The last one was probably a straight A12, so the A09 vBIOS must have been the cure for your problem.

 

Hey seeker_moc

Could you make me a A12 bios with the A09 vBIOS for the 1645 with 4670 at 700/850?

and tell me the difference between vbios on A09 and A12?

im still on A01

Thanks

 

Holy crap, A01..... You'll see a significant difference moving up to A12, Dell fixed all kinds of errors and some massive problems with the thermal and power management. The difference between the A09 and A12 vBIOSes is that A09 allows a higher thermal limit for the 4670 before it starts throttling. I'll mod you up a 700/850 later today when I get back on my laptop.

 

I fixed my driver issue that wouldn't let me overclock to 800/900 and i can and its 100% stable have you done a bios for those clock's ?

Also just a thought is it possible to keep the main post updated with all the mods you have made for people?

 

Go back one page, and you'll find 800/900. I'll work on updating the first page.

 

Thanks seeker_moc
so to go from the A12 with V09 vBIOS i have to downgrade right then upgrade to the 800/900 one

 

If you're not already on A12 you won't have to downgrade first.

 

but i upgraded before i got your message. i wanted to see what the performance was like

 

Can someone help me with my BIOS?

Dell Studio 1558

HD5470 clocks 750/800

I am unable to extract with phoenix tool.

Any help here ?

 

here is my bios

 

I can't get it to work either. Is it possible that Dell used a different brand of BIOS for the 1558? Do you know if it is a Phoenix BIOS or not?

 

Hmm, I wonder if this will work to ever so slightly drop the max voltages of the GT 435m in the XPS 15?
As mentioned in another XPS15 thread, the 420m gets 435m performance when OC'ed to 435m speeds, and the 420m max voltage is 0.9v, 435m is 0.96v, and the 435m runs hotter than 420m.
Which makes me wonder if the 435m can run stable in the low 0.9v range just like the 420m (since they are essentially the same chip).

 

It should work fine.

 

Has anyone done this for a 1640+4670 BIOS?

 

The 1640 BIOS is different. I tried to mod it for someone who sent me a PM about it. I was able to mod the BIOS, after he managed to unpack it for me, but he couldn't get it to flash correctly, kept giving him an 'incompatable' error or something like that.

 

So seeker moc, what is ur highest super safe clock so far? Im running on the 750/1000 and i think my paste has been cured. It now hits 85C at the highest i believe.

 

My BIOS is set to 813/1067 (650 + 25%, 800 + 33%). I consider 835/1105 (or 850/1050, though 835/1105 benches higher) 100% stable for me, though I just don't want to push it to the max for my permanent OC.

 

how hot does it get? I feel good that my GPU is better than the new XPS 15's GPU But its not as good as the 17's. I was wondering if the 5730 could match it in performance.
What do you use to test ur speeds? I want to try these OCs but i dont want it running that fast if it is going to burn out.
AMD GPU tool forces the card to work that fast. Thats what I am using right now and I was wondering if there is anything better.

 

I can get very close to the 445 stock clock benchmarks when overclocking, but I can't quite match them. Though the 5730 beats the 435 even at stock speeds. There's a huge difference between the 435 and 445.

I can hit 80C GPU max, but that's only when running both FurMark and Prime95 for 10+ minutes. During gaming and benchmarking I'm usually mid-high 60s with OC.

AMD GPU tool forces full clocks all the time, but it doesn't put any load on the card, so it's not as bad for the GPU as a lot of people try to say it is. By doing a BIOS overclock, you only change the full load clocks, so it will still drop down to 100/300 when not under load.

 

80C... Seriously? I have my intake cleaned, new paste applied. and it hits 85C using the 750/1000 clock.
Can you visit my house and fix my cooling?

 

Any news on this? Yesterday i noticed that the GF106 of the GTX460 takes 0,915V on load, so i guess that even 0,9 for the 420 is too high (and 0,96 in 435 is clearly HUGE).

 

Have you tried removing the dust filter? That should drop temps a few degrees. If not, then it's possible you have a defective heatsink, or you just got unlucky and have a GPU chip that doesn't overclock well (it sucks but it happens sometimes).

 

Could someone do a comparison of the framerate for modded and non-modded bios in a few games?

 

My temps hitting 83 at standard clock is ridiculous! 85 using ur mod. When i removed the bottom and raise the front a little with DVD cases, to make it parallel to the table, it drops to 10C. I loved that temp! So when you say to remove the filter, what exactly is the filter? The black XXXXXXX mesh?

 

It's a thin layer of black plastic with holes in it on the inside of the bottom plate. They cover up the XXXXXX mesh air vents in the metal bottom plate. They peel right off like a sticker.

 

oh okay i thought it was a film but its just that black thing easily visible when at the bottom cover? oh and i meant it dropped by 10C. my god if it could drop to 10C!

 

Hey seeker, thanks again for all of your work on these. I just removed the sticker/screen and got the 10C drop. I guess I never really looked at the underside of the bottom plate because I thought all of the screws would fall out (didn't know about the washers, etc.). I thought you were talking about the screen at the back of the computer that gets covered up my the monitor. Anyways, I was wondering if you had the above BIOS still? I deleted mine and it is no longer on Mediafire. I wanted to give it another shot. No need to redevelop/reprogram this (because the one I have, 800/900, works fine) but if you have it still, I would greatly appreciate a repost on Mediafire. Thanks!!

 

@seeker_moc

Hi,
I'm trying to mod an HP Elitebook 8530p notebook BIOS.
- Default MXM II VGA card: ATI Mobility Radeon HD 3650;
- New MXM II VGA card: ATI Mobility Radeon HD 4670 (taken from an MSI GX623 notebook).
Other cards tested:
- Nvidia Quadro FX 770M (working - card is in the original HP whitelist);
- Nvidia Geforce 9600M GT (not working - notebook won't boot - black screen).
Strangely when the new card is installed the notebook boots and starts Windows XP normally ignoring whitelist (the 4670 is NOT in the allowed whitelist cards! With the 9600MGT it won't boot).
I could also install the modded INF ATI Cataltyst drivers, restarted Windows and the desktop came up with the right resolution.
Seems that everything was ok and the damned HP whitelist were defeated but... PROBLEM:

After few minutes (2-3) from the boot fan starts make noise and the speed remain constantly higher than normal even if notebook is in idle.
Leaving the notebook in idle or simply using internet or 2D applications the otebook works good but always with the fan at a medium speed (with the original ATI 3650 card the fan were very very silent in idle).
Trying to load 3DMark 2005 the notebook shuts down suddenly after few minutes APPARENTLY due to a temperature issue, with the fan at full speed.
So I install NHC (Notebook Hardware Control) and as I thought the detected CPU temperature was the same when was installed the original ATI 3650 card, and is always about 40-45° using the notebook for normal non-3D applications.
Plus, raising the keyboard and touching the copper heat pipe over the CPU and GPU I'm SURE that the temperature is THE SAME either for both MXM II cards.

So... CONCLUSION: the HP BIOS doesn't "read" correctly the temperature sensor of the new VGA card and so the fan speed is raised to an intermediate state.
I'm not even sure if the PowerPlay settings works correctly... GPU-Z sensors detects a clock frequency of 220 MHz core and 250 MHz memory clock when the notebook is in idle or when using non-3D applications.

Next step... WHAT I WOULD TRY TO DO:
I think it might not be enough to mod "normally" the BIOS as if treating the MXM II slot as the MPCI-E slot of the WLAN cards...
Acquiring information on the many visited forums in the web seems that I should load the entire new MXM card VBIOS into the HP BIOS.
Before doing this I tried to recover the original HP BIOS by the WIN-B keys procedure at boot, and it works good... plus the notebook is still under warranty, so I'm strongly resolute to try with the fix.
HP BIOS is an Insyde BIOS, I've downloaded many tools to try the mod but the more appropriate seems the "Insyde EzH2O v2.1.0.4"; the problem is that I'm a newbie at this point and I don't know how to approach the procedure... I need more advice from better prepared users on this argument!
I already have:
- HP Elitebook 8530p/w newest BIOS (F.12);
- Original ATI Mobility HD 3650 VBIOS (extracted with TechPowerUp Radeon BIOS Editor v1.26;
- Original ATI Mobility HD 4670 VBIOS (idem);
- Many other tools as ATI Winflash, GPU-Z, ADDCC, HxD Hex Editor, RW Everything, etc.
but now I'm in TOTAL CONFUSION!
Are months I'm trying to find a way to mod the HP BIOS to bypass their damned whitelist... any suggestion?!?

ANY HELP WOULD BE APPRECIATED!!

Thank you.

--- sk0rpi0n -->

 

I wish I could OC my 4670 but as it is my 4670 hits 94c throttlelimit (a09) while playing BC2.
This with the XPS on a platform to allow better air intake AND with the LCD down (external screen) so the vent isn't blocked.

STILL IT GETS SO HOT IT DOWNTHROTTLES!!!! AAAARG!!!!!

 

I was away from my laptop the last few days, so I couldn't get around to this yet. I'll repost it tonight or tomorrow.
