Homer-Mix Posted June 24, 2008 Posted June 24, 2008 Hi guys I'm having trouble getting my E6600 to 3,6 GHZ(400*9) 395*9 is running 24H primestable, however, when i get to 400*9 Prime will end up in a random BSOD after a few hours(no errors, just a blue screen). System specs are in the signature. I'm running 395*9 with a load vcore of 1,472 volts, Core temps are on the low 50s after several hours of prime. I already tried to up the vcore to 1,55, (G)MCH voltage +0,025(or 0,25, don't remember) and FSB voltage +0,2. temps were around 55 degrees, so no problems so far. Ram is running with the 2.00A strap so that it would run @800MHZ 5-5-5-18 when I go for 400*9. Upped the voltage to 2,0V just to be sure that it's not the issue. I also tried to run prime with 401FSB, to make sure it's not a FSB hole I'm in. My settings: Robust Graphics Booster [Auto] CPU Clock Ratio [9 X] Fine CPU Clock Ratio [+0.0] <-- dont' have this one CPU Frequency 3.60GHz(400x9) CPU Host Clock Control [Enabled] CPU Host Frequency(Mhz) [400] PCI Express Frequency(Mhz) [101] C.I.A.2 [Disabled] !!

The Smith Posted June 24, 2008 Posted June 24, 2008 What's your RAM ? Some need 2.1V to operate properly. I guess on the EX38-DS4 the "normal voltage for DDR2 is 1.8V ? Share this post Link to post Share on other sites More sharing options...
Homer-Mix Posted June 24, 2008 Posted June 24, 2008 (edited) It's crapy MDT ram. it needs the stock 1,8V for 5-4-4-12 @ DDR800 and maxes out @ DDR900 with 1,9V. Uping the voltage doesn't help here. And yes, normal voltage is 1,8. The 0,1 overvolt give me a VDimm of 1,92V. This is more than enough for the Ram to run @ stock. Edit: the system runs perfeclty fine with 400*8. so the ram should not be an issue if i'm not mistaken.

gotdamojo06 Posted June 26, 2008 Posted June 26, 2008 http://valid.x86-secret.com/show_oc.php?id=238954 I am trying to remember what I had used as far as settings go for that, been a while since I have played with the E6600... If you could go into the H/W monitor and post what your volts are at 399x9 so that I can help you with those. I have a feeling that its your NB that needs to be upped, however I want to know what the voltage is sitting at before adding anything Also what is your FSB before you changed any voltage settings for that, I have not used that motherboard before, however I have used my share of Gigabytes and my ASUS x38 needs 1.360 for the NB and 1.120 for the FSB for a 400x9 on the E8400 Have you tried to loosen your RAM timings at all? Can you post a screen shot of CPU-Z on the main screen as well as the SPD and Memory screens? Share this post Link to post Share on other sites More sharing options...
Homer-Mix Posted June 26, 2008 Posted June 26, 2008 Seems as if i got it now. I put every voltage on normal(which means-auto voltage on the (E)X38 boards, don't ask me why) and upped the Vcore one more notch. Heck, this CPU needed 0,09Volt for 45 MHZ more OC. Ram runs @ DDR-800 with [email protected],8V. Prime ran 25 hours. Seems good to me. Now i'll try to get this crap ram working at 450*8, but i would be surprised if it would really work *lol* Anyways many thx @ Smith and gotdamojo Share this post Link to post Share on other sites More sharing options...
gotdamojo06 Posted June 26, 2008 Posted June 26, 2008 sounds good, glad that everything is good Share this post Link to post Share on other sites More sharing options...
