399:799 or 400:801 ? Tags: DRAM Frequency Overclocking Last response: November 9, 2011 4:14 AM in Overclocking Share patlav1980 November 9, 2011 2:08:05 AM Evening all, I'm in my BIOS atm and am working on OCing my E8400 from 3.00 GHz to 3.60 GHz. I wanted to set my: FSB Frequency to 400 and my DRAM Frequency to 800 but it seems not possible. Instead, I have 399:799 or 400:801 which is not 100% synchroneous. Having DDR2 800 MHz memory, should I go 399:799 to make sure I don't bust the 800? Thanks More about : 399 799 400 801 saint19 a c 278 K Overclocking November 9, 2011 2:29:47 AM Which of those is stable? There isn't almost any difference between both patlav1980 November 9, 2011 2:34:57 AM This is my 1st attempt of changing the bios. I'm in it atm (using a 2nd computer to read various guides and repond here while doing it) Related resources First-Time Overclocker, problems with E6750 and DDR2- - Forum Unstable E6750 FSB - Forum update freezes computer - Forum Monthly News Statistics for rec.photo.digital: month of Ap.. - Forum http://www.tomshardware.com/forum/ [...] king-guide - Forum Can't find your answer ?

As I said, there's not almost any difference. patlav1980 November 9, 2011 2:41:57 AM K thx. While I have you here, Tom's guide ( http://www.tomshardware.com/forum/259899-29-core-overcl... ) says I should just leave VCORE as well as the other voltage options on AUTO for my 1st attempt. Is this a good way to go? Seems legit saint19 a c 278 K Overclocking November 9, 2011 2:44:51 AM You leave the vcore on auto to check if can be stable without change the voltage, you can try it but if it's not stable you need rise the vcore voltage a little for get it stable. patlav1980 November 9, 2011 2:49:37 AM Makes sense. I will leave it on auto since I installed an aftermarket CPU fan (CM Hyper N520). Will let you guys know how it went. Tks! saint19 a c 278 K Overclocking November 9, 2011 2:51:12 AM ok, let me know the results patlav1980 November 9, 2011 2:52:58 AM Ack one more question. Should I enter the standard values for the following instead of leaving them on AUTO? CPU PLL Voltage FSB Termination Voltage DRAM Voltage NB Voltage SB Voltage Colck Over-Charging Voltage I understand about the CPU Voltage but wouldn't it be dangerous if by leaving let's say DRAM Voltage on AUTO it would automatically bump its voltage so high that it would damage my memory? jsc a c 197 K Overclocking November 9, 2011 4:03:47 AM For the voltages you list, Auto will simply select factory default values. Other settings will not cause them to change. You can make small adjustments to improve stability, but you should know what you are doing when you do change them. patlav1980 November 9, 2011 4:14:57 AM Ok thx. I sorta have 2 threads running on this (main thread is called: My E8400 overclocking project). Think you could transfer the posts in here over to that thread? If not, maybe just delete this one as I'll continue in the other one. Thx! p.s. I launched Prime95 (blend test) *crossing fingers* Can't find your answer ? Ask !
