Typical issues w/ P5B-DLX?? Help please

[newls1]

OK, I just started OCing my new P5B-Dlx using a E6600 L630A832. Using 401x9 for a 3.61GHz OC windows seems great. I installed XP using the OC, and PC runs for hours w/ out issue. I go to SP2004 to check stability and PC shuts down in under 2 seconds. I had the Vcore up to 1.425 in BIOS. What the hell? I dropped the multi down to 8 and used a 425 FSB and SP2004 runs fine:confused: Using only 1.395Vcore. I have tweaked all the voltage options, but someone PLEASE try to give me ideas here. Everytime I use a LOWER multi, Windows thinks im running @ 3.87GHz which is truly not correct. At this present time im running SP2004 with a 364 x 9 = 3.27GHz with 1.4Vcore and all seems fine so far. I really want to have a 3.5+GHz OC here, can someone help me? Thanks

Unless you have good cooling, your not gonna get 3.5ghz+ stable and a reasonable temperature unless you have a really good chip. Another thing is OS running (appearing to anyways) stable for awhile is not a good thing to go by, normal use of windows or whatever your using isnt going to tell you anything about stability, a stress test (orthos or whatever you use) or a highly demanding game will tell you the most about how stable your system as a whole is. try 400x8 its 3.2 but should be stable at around 1.3-1.35v which is a good OC with good temps.

And as for windows reading your doing say 400x8 which is 3600 effectively using the default multi of 9x it would be 3600, its only reading default multi x FSB which in my case is 400x9 which reads 3600mhz.

Right now Im @ 3.46GHZ running my ram with a 4:5 ratio for 455MHz using 1.4volts and a multi of 9 (stock) My cooling is a scythe infinity w/ 100CFM 120mm fan and a open bench case. Orthos small ftt test is stable now for almost 1 hour

4:5 divider thats your first problem, run it 1:1 and you wont have any issues from that department. Whats your temps like?

If I keep it @ 1:1 my ram will only be at MOST 410MHz? I find using this divider really makes my ram PERFORM. This Gskill HZ ram seems to be stable with 2.25V w/ 4/4/4/12 @ 975MHz. My DS3 board would never allow this ram to operate this fast. It seems that 3.52GHz is where im at using 390fsb x 9= 3.51GHz 4:5 memory. here is a pic: http://img185.imageshack.us/my.php?...untitledpb3.jpg

Also, why is it that when I run 1:1 with my memory, on the POST screen it shows my ram @ PC4300? When I use my 4:5 divider it shows it @ PC5300?? Im using PC6400 G.skill HZ ram..... I think I really like this 4:5 divider as it gives me 7830 scores using sisoft sandra memory bandwidth test.
