Sharp Posted November 22, 2006 Posted November 22, 2006 I bought a new CPU, went for the San Diego 3700+ as it meets all my requirements. There were 2 choices, E4 or E6 core. I went for the E4 core revision. Many sources state E4 overclocks better. CPUZ screenchot. The default Vcore voltage is 1.35v-1.4v - I set the bios to 1.325v and it shows up as 1.3v. - In CPUZ and ITE Smartguardian it shows as 1.28v I will assume its 1.3v. Why did I lower it? Wanted to see if it would work with less than 1.35v. Preliminary testing (I haven't done anything serious yet) - 3 hours memtest - 1hr 20min Prime95 - Many hours of CSS - 3Dmark03 - Everest Home edition All the above was done with the OCZ EB Platinum PC4000 2x1GB 3-3-2-8 kit running at, - 200Mhz - 2-3-2-5 - 2.6v - Orange slots That is all so far, I will update this thread as I make progress.

red930 Posted November 22, 2006 Posted November 22, 2006 Good luck overclocking. Those things are beasts! But mine needs 1.47v to get to 2.75GHz Not the greatest stepping. Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted November 22, 2006 Posted November 22, 2006 Good choice with the 3700. It's def my favorite single core especially since my old one did well over 3ghz on air with relatively low volts. What stepping is it?

Guest RohypnoL Posted November 23, 2006 Posted November 23, 2006 E4 is a great clocker. I can hit 3195 in windows x86 but as soon as I go into clockgen and add one more FSB to 3200 something, instant BSOD =( Share this post Link to post Share on other sites More sharing options...

Search the forum, if i remember well there's a thread about those programs. Share this post Link to post Share on other sites More sharing options...
Emery Posted November 25, 2006 Posted November 25, 2006 Yeah me too, cpu-z and smartguardian are showing me lower voltages than the bios. Im also working on my 3700+ Overclock. Is there a reason for the Orange slots ??? You just make me curious about those. Anyway, keep updating this post. I want to see how far your gonna push your 3700+. And can you tell me what is your videocard? Heres a screenshot of my CPU at the moment. I had some work to do this week so I didnt had the time to make it stable at 2700Mhz.

dr_bowtie Posted November 26, 2006 Posted November 26, 2006 I think all the NF4 boards under volt the cpu...On mine I can count for .04 in ITE and .02 in bios... When I set mine at 1.400+104% it shows in cpu-z and ITE as 1.4vcore... not a big problem as long as it's cool and passes prime i dont really care what the real volts are... I have got a couple of 3700's i picked up off the forum a KAB1E and a KAB2E and depending where you look one is better than the other but it's either one depending where you look.... i have heard the 1st one then the second one...so I'll find out soon.... they seem pretty nice cpu's... I kinda jumped forward then backwards....I leaped from NF2 to NF4 (sig) and then to the NF3-250... and I tell you what...I really like my NF4 rig but right now I have been spending alot of time on my nf3 rig....it's my main media pc as well as my internet surfer... I have it in my shop in the basement and man I tell you what... how did I miss those....? This 3400 is sweat.... and runs cold as heck...but as soon as I get the 7600gt in the NF4 rig,,might be another story...? Share this post Link to post Share on other sites More sharing options...
Sharp Posted November 27, 2006 Posted November 27, 2006 Internet host must be having problems that is why my sig is not there. gfx card = Point of view 6800GS 512MB. A small update, I was planning on showing 2x512mb BallistiX @200Mhz (tweaked timings) vs 2x512MB BallistiX @250Mhz (tweaked timings) But the kit does not work in DC mode anymore. Both memtest stable but fail prime95 in DC mode. So now it is only going to be 2x1GB EB plat @200Mhz (tweaked timings) vs 2x1GB EB plat @250Mhz (tweaked timings) Might try more than 250Mhz, will see how it goes. I am very busy with course work and work so not much is going to happen yet. Share this post Link to post Share on other sites More sharing options...

So I changed this Read to write delay (tRWT) = 1 to 2. Test #8 no longer fails he 4 cycles. Obviously I am going to run it for 11 hours again this Saturday.

27floyd Posted December 16, 2006 Posted December 16, 2006 test 5 and 8 are really the only ones that you need to do, they are the hardest on the chips.. Share this post Link to post Share on other sites More sharing options...
27floyd Posted December 16, 2006 Posted December 16, 2006 I have the E6 version only because thats what came in the mail.. I would have taken a E$ but some say the mem controller on the E6 is better. so im not to unhappy with it. Share this post Link to post Share on other sites More sharing options...
