Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 Hi People! First I want to say: "Hi All!" becouse I'm new here. I read the A64 Definitive Overclocking Guide, and it really helped my quite a lot, but I still have some problems: I know people, from other forums, who are able to clock there X2 3800+'s to ~2.9GHz... This is an insane speed! And I loved to reach something like that, so i bought my new system... As you can read in my signature: DFI LanPary NF4 Ultra-D AMD Athlon X2 3800+ @ 2.74GHz 2x512MB GEIL PC4000 Maybe you are thinking something like, what are you whining about? 2.74GHz, that a great speed! -Sure it is! But, that 2.9GHz, or something like ~2.85GHz would make me really happy! I tried some things, like loosening the memory timing, dropping the memory divider (even tried DDR200) but that doesn't really make difference... Could it be possible I just hit my "max"? If you need more details on my memory timings, or other settings, please let me know! Thanks in advance people, an oh... Sorry for the long post :angel: Take Care!

Gipse Posted April 30, 2006 Posted April 30, 2006 How much vcore have you tried, what cooling? Keep in mind that only "few" 3800+ will get that high... Gipse Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 Hi Gipse, thanks for your response! I have the V-Core on 1.55Volts, but setting it to 1.64, or even 1.88 doesn't make any difference... I use the CoolerMaster CPU Only Watercooling (Mini Aqua Gate) Like I said, I'm pretty happy with these speeds, but you know, maybe with some pro advice I'll get it a few MHz higher...

Rik, First….Welcome to the Street. You came to the right place for support on your DFI motherboard and your OC challenge. I'm curious what temps do you get at “1.64v or even 1.88v”. :eek: Which IMO are not recommended! Over volts does make a difference in the death of your CPU. It is just as quickly to kill your CPU with over volts as it is with over heating. You’re running water cooling so you’re conscience about temps. Why not be conscience about over volts? Duel core can be more challenging to over clock and unfortunately you may never get there. Are you stable at 2.74Ghz? Keep reading and searching Here is some more good reading about temps. Temps Too High? tasr Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 Hi tasr! Thanks for the welcome My temps were also pretty good (if I say so myself) at high voltages, like 1.64 or even 1.88v never came above 45 degrees Celcius... But I found out my system don't like high voltages anyways, when I take it above 1.7v, no matter what speed, sometimes I just get instant hangs... No BSOD, no system lag, just instant hang... By the way, what you are trying to tell me is that -- even on low temps -- over volting is also "killing" my CPU faster than normal? My PC is "rock-solid" at 2.74GHz... (12+ hours @ Prime95 Blend Torture) My temps @ 1.55v are: Idle: 28 Celcius Load: 34 Celcius Thank you for your time! Rik Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 Could it be my BIOS? I downloaded the ISO created by Tmod (the Flash CD...) and what BIOS is recommended for OCing, or is that a stupid question? As the A64 overclocking guide says there is no best BIOS... Thanks all!

lowboy Posted April 30, 2006 Posted April 30, 2006 Your saying that you ran 2instances of prime95 for 12hr at 1.65-1.7V with a load temp of<45C. Your post did not mention dual prime as running 1 instance with a dual core shows nothing. Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 I ran 1 instance of Prime95 for 12hours at 1.55 Volts, with temps around 34C Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 By the way, is there anyone on this forum who also owns an X2 3800+, I'd like to know their OCs... Another by the way... What is an good stepping for the X2 3800+ , mine is: Family: F Ext. Family: F Model: B Ext. Model: B Stepping: 1 Revision: BH-E4 (according to CPU-Z) I've seen someone with exact the same (Ext.) Family, (Ext.) Model, Stepping and Revision hit 2.9GHz... Priming 2.76GHz now, I just changed some timings... t.b.h I'm really getting sick of that... :drool: Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 Lol, seems I am the only one still posting this thread... Anyway, for the readers (and I hope helpers): CPU: 2.76GHz @ 1.55v Memory: 250.9 MHz (DDR500) -- So this must be Ok... CPU/1.1 CAS#: 2.5 RAS to CAS: 4 RAS Precharge: 3 TRAS: 0 Bank Cycle Time: 12 DRAM Ilde Timer: 32 Command Rate: 1T Prime95 fails @ 19 minutes Also tried 2T, don't seem to make much of a difference... Can anyone please give me some advice? :drool: Share this post Link to post Share on other sites More sharing options...
lowboy Posted April 30, 2006 Posted April 30, 2006 Run 2 instances of prime to know your stable here is how :http://www.dfi-street.com/forum/showthread...ghlight=prime95 Share this post Link to post Share on other sites More sharing options...
Rik.Reinink Posted April 30, 2006 Posted April 30, 2006 I'll let it run overnight (its 11:33 PM now here) and I'll post my results tomorow. Thanks lowboy! Share this post Link to post Share on other sites More sharing options...
