The Official X2 Overclocking Discussion Thread

hrm, well i ran Prime95 Blend test overnight and it passed with ram at 3-4-4-10 1T at 2.9Vdimm 1:1 250X10 (Neo 2 overvolts to 2.9 when put at 2.85). Although considering these Ballistix stock volts are 2.8Vdimm at 250Mhz i backed it down this morning only to see it fail Prime Blend immediately at 2.8Vdimm wtf? I put it back up to 2.9Vdimm and it passes. Could the memory controller be causing this kind of problem or is it the ram? Should i consider an RMA to Crucial cuz it seems a bit fishy to have to overvolt the ram to get it to run in spec?

u better try it in a diff board before you rma budwise, 99% of the sticks I have seen hit 280 easy.

the board monitor isn't nescarrily accurate, so frankly, if it works at 2.9v then thats fine. See how it overclocks before you get upset.

don whered u get urs from bro, u have an awesome chip dude..
Take her nice and slow and shes gonna give u 2.8 i beleive

I just ordered mine from monarch and Im going against the grains and getting el cheapo mobo asrock but I think this combo is gonna pwn :toast:
IU hopemy chip is something like urs..

Also what kind oif burn in have u done on it?
Put it in and burn for 24? or maybe 2.1 then burn\

I wanna try ur guide because either u have god chip or ur technique is good for that chip..

im in the UK, it was OEM from a shop called Lowestonweb.

My burn strategy was like thus. I really just fit it round my schedule tbh. I can't sleep with the noise it makes, and i'm not meant to have it on during the day when i'm not here. (might burn the house down apparently....) When i got the chip, i raised it up to 2.1ghz straight away, and dual primed for an hour. Stable, so i repeated this up to 2.5ghz, keeping volts the same. At 2.2ghz, i left it running prime for 12 hours as i had the time for it.
At 2.6ghz, it became unstable. I worked out i needed 1.31v to run so windows would be reasonably stable, although prime ran for 3 mins then errored. I then left it running cpu-burn for a couple of hours. Came back, and it was stable in prime. That is basically how i got it stable at requisite mhz, and i just did it again to get 2.7ghz stable. Ran cpu-burn for an hour, and bingo, stability is mine. Wouldn't run prime more than 3 mins, now is going on endlessly. Will keep going until i hit the big 3.0ghz, then i'll make it stable as possible. Preferably 24hr prime.

Hopefully that makes sense. If it doesn't, PM me or MSN me or something, and i'll make it clearer. I'd like to belive that my burn process helped the chip a bit, although tbh i guess i was lucky to begin with at getting such a fine chip.

Have U ran the the Burn-in in dual mode or single?...I`ve tried mine burning with SP2004 but for now I can get stable on endless SP2004 at 2,6ghz and 1,552V... :rolleyes:

Regards,
Primoz

dual mode obviously. Not much use doing it single.

One of my cores is really terrible and constantly fails SP while the other will go on forever. I have started to burn it in and it seems to be getting better.

Am I right in saying that if you have one core that is not as good as the other, if you just run tests on the weaker core then it will improve it over time?
Because I have one core that needs loads of volts once it goes over 2.6 and becomes a bit flakey, whilst the other goes up to 2.8 with no problems.

Just got my X2 to 3190mhz after tons of dram/cpu tweaking. Currently running at 1.5vcore (1.73 still doesn't let me hit 3200+).

Anyone know if burning my X2 in will give me a higher OC?

Thanks

Burning in my X2 only improved my max OC by 20 Mhz but I was able to run at a slightly lower clockspeed with less voltage.

i love this thread. Will setup my rig this weekend! X2 4400+ hmmm

Lol, my X2 3800+ (0529 SPMW batch 179) is prime stable @ 2500 mhz with stock voltage (1,35v). Not bad :cool: :rolleyes:

More results coming soon :p:

What seems to be the best bios for X2 cpu's?

704-2bt is working great for me.

623-2 is da bomb!! :)
2600Mhz @ only 1.26v (and testing my 3800+ with my vapochill within a few days :D)

704-2BTA works best for me.

I just stepped into the game as well currently dual priming at 2500 default voltages, dual stress primes :)
gonna go for about an hr then push for 2550 then 2.6
ima go till she wont let me anymore
As for this asrock mobo havin problems I havent had one yet
I went all way to 2450 with 1.3
had to bump to 1.35 prob coulda did 1.325 but skipped right over it and want to see how high I can go at stock..
unfortunately I cant raise vcore anyway so 1.35 is my max until new bis comes out, so looks like im in good shape as is..
als dual priming with hsf on at 38c which isnt bad, I think when I decide to go topless its gonna own, and lapp the HS :woot:

I have reached 2.6ghz Dual prime stable at 1.552V but can`t get any further...it seems to be the mem controller weak...cause I changed the ram divider to 166 and get no errors at 2.65ghz at 1.6V...before get an error after 2-3 minutes...Will try sth else...but can`t get to work at 2.7ghz stable even at 1.64V... :slapass:

To all that running at stock volts...do U use a divider for ram or what? Cause I checked my ram in memtest and it is stable at 265mhz @ 3,4V...but have problems to run Super_PI or Prime... :confused: I managed to do Super_Pi 32MB @ 2,7ghz with ram divider 183 but when tried out Prime95 it stops... :rolleyes:

well here it is, seems my best dual prime stable speed with 1.35 is only 2510 so far :(

sucks bawlz now I wish ida got me a ultra d instead

Theres still time to RMA which I might do, i got 2 weeks from today :slapass:


Oh and this is all 1:1 2t :(

I would be very happy if can get with my X2 3800 at 2510 with 1.35V

ive been burnin her in past 2 hrs at 2.4 with 1.3v :)
I know I have a good chip, its that I have a mobo that wont allow for higher vcore to be thrown at the cpu, and I dont have enough confidence yet to do the vcore mod, im thinkin about it though

I have a x2 3800+, I think I have a problem with Norton Antivirus 2005, it appears to be using >50% cpu which means it is multithreaded????

Or is it just stealing my cpu's execution units doing nothing?
I remember norton was never using >50% cpu.

This is when I updated it through liveupdate.....

cant help ya there bro I had a free thing for nortons so i installed it and it gave me problems so i went back to mcaffee 2005 internet security suite. she uses low %age

Looks like my comp is dead at home...have leftet it burning-in at same speed as usual and now I have no response...when I press reset or power button everything is dead... :shocked: hope will fix it when come home from work. Keep your fingers crossed for me guys... :rolleyes:

What happened? Is it just frozen or is it off and wont turn on?
