Asus p5q premium 8gb ram freezing gskill 8500 model

There is no point in going Q6600 over E5450 (they both have the exact same multiplier), and 45nm means Xeon will clock higher by default.

If they have the same multi then yeah it shouldn't make much of a difference at all.
I knew the e5450 was a 1333mhz cpu and the q6600 was a 1066, But if the multi is the same than they will reach the same speeds at the same fsb.
for some reason i assumed they both had the same stock speed which would have meant the q6600 had a higher multi. But for overclocking they are the same then.

the only issue i ever had overclocking a q6600 was the motherboard hitting a fsb wall.

Any way id bring the fsb down a bit on the board as said above. 433 444 or 450 its probably going to help stability a lot.

Good info there in my case im trying to find the max fsb speed before it falls on it face as i havent found it yet as i know the 4x 2gb will put a strain on the nb but i know the ram can go higher as i have tested it before i only ever seen a few e5450 overclocked between 4ghz to 4.5ghz range most on gigabyte board and a good few on asus p5q series even a video on youtube with 4.2ghz but no bios settings to compare so theres goes the guessing game.

I only ever got to 479 on fsb on the board i have now as it was ages ago as it crashes as that was related to ram timing were in auto. But now i can understand each timing does so yea i could be reaching my goal of 4.4ghz or 4 3ghz in no time once i got that in the bag i settle for 4ghz

Try different Strap setting or Transaction Booster.
Higher NB Voltage should help as well.

Highest I went on P45 with 8GB DDR2 was 512MHz FSB.
I "cheated" by using EP45-UD3P board though
It went through Time Spy at 490MHz (4,41GHz)
PS. That was on X3370.

At the moment i adjuisted strap to 5:6 (333) in bios the nb is 1.46v the cpu gtl 0/2 0.665 cpu gtl 1/3 0.675 vcore is bumped up 2 clicks as most of the settings are the same as i posted it on page 4 as it running 4 33ghz cinebench record 483 max vcore just jump from 1.264v to 1.280v from idle to load temps climbed up about 5c peaked 51c

I will test for gaming to see anything crashes during resident evil 2 remake

Game running found an area where it put the cpu between 70% to 90% load so far no crashing only issue is stuttering only when i go from one room to another and turning with view as i can see screen tearing i can live with that as it doesnt bother me that much

I been testing all night yesterday decided to set the second sub timing in auto to see what the motherboard will set to via memset it boosted the read, write, and copy in aida64 around the 10000mb range with latency dropped down to 68.8ns to 69.1ns range, the northbridge voltage bumped up to 1.50v. With the second sub timing in auto it made a bigger improvement in resident evil 2 remake it alot smoother with less stuttering

Been testing some games lately including dirt 2.0 was getting crashes thought it was gpu freaking out but it wasnt it was mostly to do with dram clock skew in auto no matter how much voltage it getting doesnt get any better. So i ended up thinking of a balancing act is if i do ratio 1:1 @ 989mhz i have to advance clock skew a1/a2/b1/b1 to 100ps the games stop crashing like nothing happened now when i go for 5:6 @ 1150mhz i have to delay clock skew a1/a2/b1/b2 to 200ps the games get better improvement with mixed low/mid/high settings. Currently it running 4.3ghz @ 1.320v max temps during games hit a high 55c i will upload a better bios settings sometime tomorrow
This asus p5q premium, gskill f2-8500cl5-2gbpk x4 and xeon e5450 surprises me every time. Gonna push for more overclock some day to see which cpu, ram, or motherboard will hit a wall as i havent even hit one yet
