Overclocking and 8GB Ram concern

Hi all.

I have an E8500 on a GA-EP45-UD3P running 8GB ram (I do photoshop and a lot of multi tasking so I just recently upgraded to 8GB from 4GB)

I've been interested in learning how to overclock and give a lot of repect to those that know a thing or two.

When I first built my computer the CPU was 3.16GHz and 4GB ram at 1066Mhz (5-5-5-18 ) all stock.

I have slowly tried different things and this is what I'm at right now:

CPU OC to 4Ghz - 9x 450Mhz
8GB Ram running stable at 900Mhz
Auto timings are 5-6-6-17 according to CPUZ
Sys Multiplier 2.00D
CPU at 1.3V and Ram at 2.1V
Idle temp for CPU is about 43C and under load seems to not go over 60C to much.
My MCH latch speed is 400Mhz (if that means anything to you all)
I have a 1:1 ratio with my FSB/DRAM.

I found out that this OCZ ram that I have does not like to run on my board at 1066 with 8GB ram.

I should have just bought 8GB of PC6400 800Mhz ram in the first place and saved my money.

I'd love some input on my set up here and some help in understanding timings.

Thanks for you time!

Why do you want to overclock 8 gb of ram your not even going to fully utilise o.0

I would say, if you don't have/know of a reason to OC your hardware, then don't. There's a reason why every bit of marketed as OCable piece of hardware out there never fails to mention that OCing will void your warranty

My reason is because I can. Anyone going to try and overclock should have the sense to know that it can void a warranty. Seeing how I'm the builder of the PC I warrant the thing.... I break I buy. Maybe I'm on the completely wrong website for this sort of stuff.....Cujo31

I would say the vast majority of people posting here fail to realize this when it comes to OCing. Looking at the QVL for that board (rev 1.0), I see a OCZ p/n OCZ2N1066SR2GK listed at 1066, its for 1gb sticks, but I don't see why the 2gb wouldn't be supported either. QVL's are definately not all inclusive. You should be able to tighten up those timings to say, something along the lines of 5-5-5-15. When it comes to timings, the lower they are, the higher the performance you will see. Set them too low, and you'll see a loss of data I/O of the memory. Think of it as valve float on an engine. What voltage are you running them at? Those should be able to run at 2.1-2.3v

Thanks for the good replies guys. @Snotweasel530, I'm running the ram voltage on auto and Hardware monitor shows them running at 2.1V. Should I manually set this? I'll set the timings to what you suggested. They were at that when I had only the 4GB of ram. Set to Auto the 8Gigs are at 5-6-6-17. I'm running with a rev 1.6 board. Maybe the same deal though. Thanks for the info! @metacritical, I'm glad I'm not the only one with this problem. I've been having trouble finding info about it online. I'm not sure how to get my ram higher than 900mhz, without over clocking the CPU. Seems to be locked in a way. Maybe just the gigabyte board?Cujo31

Bump up the clock until it becomes unstable, then adjust the voltage. Bump up the clock again until stable, and you will have your max clock.
