Diamond 4870x2 Futuremark Overclock Testing

[RCG_Bex]

I hope they send em 1 of these baby's out to replace my dead 3870X2 which last 1 month before it blew - went pop, sparks flew and smoke puffed... Asus were absolute dicks about it and eventually after 3 months sorted me out with an RMA but I'm still waiting. 4months has now passed... (1 month since it left my house) :'(

can't wait to buy one, maybe two

I may try one of these myself. I had planned on trying GTX 260 SLi and 790i was a nightmare for me. So I am going to be on an Intel chipset. When the regular Q9650 is released I may get that, Intel X48 and a HD 4870 X2.

4G with 840/1000 3Dmark03 = 86867 no LOD, using latest 4870x2 official bios. no hotfix installed

could you run 2k3 to 850/1100 with cpu to 4ghz ?

[xMrBunglex]

4870 i can only make it run about 1.3v using bios mod. haven't test the new method of bios mod; which i did on x2 this time; on 4870.

you can't just casually mention something like that and then stop posting on this thread

the rest of the world says you can't soft mod a 4870's vGPU at all. how did you do it? we need your BIOS!

MAybe this is an answer: there is a BIOS that lowers 2D voltage, and so far looks to be confirmed on ~1.063V (-0,2V). Since that's 0,2V lower than stock 1,263V, maybe you can push it to +0,1V as well (1,363V). You can find a lot about this BIOS in TechPowerUp "2D-low voltage" thread over here. I still don't have upgraded cooling, so can't confirm, but you can try if you wish!

EDIT: Oh, also, there is RBE 1.13 out, which looks to be "patching" any BIOS with this same voltage tweak, so you can try adding the "tweak" to your BIOS of choice, and than adding higher voltage. Good luck! Will be waiting for results

[guess2098]

i am not sure the softmod voltage is working or not. it give me better overclock but not sure it is due to voltage since i change lots of bios code

[T_M]

Well how about you share how and let someone try?

[dejanh]

Really, care to share???

[OnDborder]

What method did you use to oc the card? Rivatuner, rbe, etc.

[lowdog]

Well???????????????????????????????????

Nearly 2 months and the op can't give us the info on the bios mod

[STEvil]

My card seems to run at 1.26v stock (assuming rivatuner is to be believed, have not prodded with a multimeter)... maybe X2's can use higher volts?

Looks like we'll never know as guess2098 seems to have been banned for some reason.

I'm facing a little problem here - i put latest 9.1 driver and my score falls with 1.300 points. I mean, with 460FSBx8.5 i had ~22k(a bit more), now with 9.1 and 475FSBx8.5~21k(a bit more), the card on stock. The problem is, i can't remember which driver was before. Is there any explanation for this, or i should install all driver and hotfixes from 8.10 to find which is? With the new driver sm2 and sm3 is lower.
