Help me get a X2 3800+ to 2800Mhz please !!

My heads clear now.
Shocky if you change your bios to 1004 it will give you v.core options up to 1.65v.
Ill see if I can find the thread on EOC and give you a link.

My X2 3800 was stuck at about 2.76 till I removed the IHS.
Removing the IHS will almost deffinately get you to 2.8 but you would loose value on the chip if you decided to sell.

EDIT/ I found the thread on EOC, link below

Interesting, bit late to start flashing but i'll definately give that bios a try tommrow ! :D

Temp isnt really that bad imo, i've seen my 4400+ up to 56C so plently of room to play with and I only think it needs a slight voltage increase.

Should the 1004 bios work ok with dual core CPUs? Why are there no custom bios made for this board, etc, latest bios with extra voltage?

Thanks btw !! :) ;)



Just has a quick search for it but found nothing.... any idea where I can download this? :confused:

had exactly the same problem as you. I was unable to raise vcore past 1.55v. I saw reviews where they had the option up to 1.65v so i assumed this was on a different bios so i tried all of them and had no luck getting past 1.55v. This was with a 3700 cpu. In the end i was sensible and got a dfi board and sold the asus on.

Also have you ran memtest at that fsb because with my asus premium i couldnt go past 270fsb. I tried 2 boards, 2 sets of memory and 2 psu's and had exactly same results and the memory was guaranteed up to 275mhz with 2.5,4,4,8 1t. As soon as it went over 270 it errored no matter what memory settings i changed. Have you tried lowering the mulit and running at 280 to check if thats stable (rule out the board and memory). Also have you tried raising ldt and chipset volts - doubt this will help but worth a try.

Also i have all the premium bioses from 1004 onwards up to 1011 beta. I wouldnt recomend using the 1004 bios as doubt it will have dual core support and large mem compatibility but might help. I did try all the bioses and none helped me go past 270fsb limit. Your welcome to them if you want them though

I reckon if you could lower those temps 5 degrees then it would be stable - have you tried turning the house heating off - lol

W00t, I found the 1004 bios ! And max is now 1.65V ! Sweet !! :D :D :D

Its at 1.52V now and its priming, 20min in and no errors so far... /me crosses fingers... :D


I'll probably just settlle with the memory at @235 with tighter timings, there difference in performance is quite small anyway, its basically 7000 vs 6600.. I can live with that,.

Might consider removing the IHS but i'm worried about the heatsink making good contact as the hight so no doubt be different..

Is it safe to have a SI-120 directly on the CPU?, will it make full contact with the cpu with the IHS off ?

***! I never got 1.65v when i tried the 1004 bios. Maybe i flashed with a different one by mistake. Seems stupid that asus would remove the higher voltage options in later bioses. Not sure about the si120 but i have the xp120 and that fits if you modify the mount and sand down the raised part of the socket on the board

Aw well I guess there was a good reason to remove the voltage options.... They don't work... :mad:

And I'm assuming it didn't make a difference to the overclock?

Don't trust software voltages.....

Nope the temps didnt increase at all, and the fact the cpu was still unstable kinda confirmed it. :p

Wouldn't putting 1.65 into the CPU constantly drasticly shorten its life?

Yes it would. But then by how much nobody really knows. Most 'enthusiasts' would upgrade there chip before finding out.
 
woow woow, hold the mojo.
Just tried 1004 with my 4400 & just got a blue screen when hitting Windows :eek:
Then again the default BIOS crashed & burned too so it might have been something to do with my nDodgia RAID array.
Took some battling to get the 1011-6 BIOS on a floppy to flash again, sheesh.
More voltage shortening a CPU lifespan ?, perhaps we should ask how many people are using the same CPU they had 2 years ago ?

how do you flash to a previous bios version? The ez-flash alt and f2 comes up with image file cannot be used because its and older version just like autoupdate. What other options are there?

EDIT: found the awdflash.exe on the support cd. I now have 004 bios :D
