5850 overclocking issue??

[OnBoard]

that was the Vmod for the 5830 from what ive seen. unless you can put up a link.

Yep, but they are all the same, 5830, 5850 and 5870 all use that same blue PCB & XFX just colored black (and maybe even powercolor/club3d with red color).

But if you don't have a volt meter, there's no point in this or any other volt mod. If it was a resistor that you could just pencil over, then if you'd be very brave with trial and error you could raise it just a bit (notice better OC, but not insane temps).

layout is different on some non ref boards (theres a V1 & a V2 pcb's floatin around)

5850 OC you say?

I have twin 5850 toxic in crossfire. System does 22445 3DMark06 with stock 965/1125 on the cards out of the box.
I can run them at 920/1245 and play MW2 but 3DMark06 will not run.

Is the Toxic non-reference enough to not have a tweak utility?

Hi guys - I just got my 5850 up & running. Im trying to overclock it but for some reason GPUtool tells me the voltage control is not supported. MSI afterburner wont let me change it either...

this is the card i got

http://eu2.sapphiretech.com/gm/images/product/gallery/0338/338_20100422_9107.jpg

due to some mistunderstanding in the shop they wouldnt value & give me store credit on the 5770 they were gonna give me - but on my dead 4870 which came out to £110 & I only had £120 in my pocket. that asside i still got a small discount. the 5850 i bought costs £245 but i got it for £235...

back to overclocking.....is there any way I could unlock the voltage controls?? I read in some posts that some people flashed their card to another brand to unlock it....


any advice would be kick ass other wise im stuck lol.

Here's the deal.... I have that same card. I have it Crossfired with a HIS reference 5850. Now with all the Reference 5850's (The Bat mobile looking ones) you can un lock the voltage controls with a BIOS change.

But with that card that you have..... it is not a Reference card. (Or meaning it doesn't have the reference PCB) So you can not unlock the voltage controls.

Now since you are not running it in crossfire you can unlock the code in MSI afterburner (Like Erocker mention change the 0 to 1 or something like that) The you can overclock the card as high as you like or as high as your voltage will allow.

Or the other option you have is to flash it with the Unlocked MSI BIOS. Which I haven't done. But according to a reliable source here..... that BIOS will work on theat Non Reference card you own. Again it won't unlock voltage control.... but it will let you get past the CCC 775 MHZ.

Now I also have heard you can flash the BIOS to the Sapphire Toxic BIOS. Because that card you own and the Toxic PCB's are the same. Again you would get the same results..... unlocked clocking but no voltage control.

There is no way on that card ..... to get voltage control except for Hardware Modding it. Which I don't suggest for every day use.

Yes it does suck..... trust me I know. I have been trying for ever to get past the CCC limit and because I am in Crossfire.... for some odd reason the MSI Afterbuner Hack won't work for me. So the only Option I have is to flash the BIOS. On a Non Reference card .... that's always risky!

Hope this helps. Good luck if you figure something out first please let us know.

My apologies but that score seems far too low.... what speed was your CPU at? I get well over 25,000 3D mark 2006 points from a single HD5850.

His score looks normal to me. It's because he doesnt have an i7. With my card clocked to 850/1300 I get around the same score as he gets which is only 200 pts more than stock.

Basically I get over 22k in Vantage GPU tests and only 22k in 3DMark06.

yeah, I understand which is why I asked about the CPU speed, I was only puzzled because before my i7 days, with a S775 Quad and a GTX260 I got over 22,000 points..... hence I thought this was a little low.... he is running crossfired HD5850's!

What was your s775 quad clocked at? I don't know if his specs were filed out at the time you posted your question but 3800mhz sounds about right for that score with 2x 5850.

22,070 points with a Q9650 @ 4.4gig and a SINGLE GTX260 @ 795mhz.

3DMark06 is a bit (much) silly, it's a CPU test, not a GPU test. More cores and faster clocked they are the bigger score you get. No matter what and how many GPUs you got with a dual core you'll never get a big score.

This with a GTX 280 clocked to 735/1512/1224 and E7200@3.2GHz
3DMark06: 14352 (SM2.0: 6323 SM3.0: 7715 cpu: 2825)
Vantage: P14943 (GPU: 12528 CPU: 35436)

Now same thing GTX 280 clocked to 735/1512/1224 but i5-750@4.2GHz
3DMark06: 22125 (SM2.0: 9302 SM3.0: 9713 cpu: 6558)
Vantage: P15857 (GPU: 12927 CPU: 49531)

Use Vantage and lose 06, it has served it's purpose

what happens to benchmarks when they die? is there a heaven for them? Like doggie heaven but not....

 

[Toadicus]

OK, Vantage runs now and I scored 19344 with my set up.

BUT once again, if i click the check box on CCC OverDrive, the brenchmark hangs on first load in.

Still can't OC video cards and have futuremark run .....

dont use ATi overdrive - use MSI after burner.

OK, Afterburner clearly the program to use. I turned the wick up to 4030MHz and 920/1125 on the Cards and scored P20920 3DMarks in Vantage!!

I know the i7 have that beat, but after searching the database in OBR, I score very high for a Phenom2 x4 unit.

Funny thing happened though. IF i changed the memory clock off of 1125 in either direction, then the clocks would reset to defualt while Vantage was loading and my score would suck. I can change the core closk up and up without an issue (short of smoke) but can't touch the memory clock......weird

Just save the profile as you change the clocks and make sure to set the 3D app profile to the one you're using. As an added fail safe enable OSD monitoring of clocks and use a hot key to force a priofile if Afterburner doesnt use the clocks properly.. I use Alt-P to get my clocks right if things don't work initially.
