It can also happen that overclocked CPU\RAM\Chipset is beyond its limits and is corrupting data before it gets written to the drive. that is a very good and interesting point...never thought of that....um... just to make sure I understand it properly, are you saying that the OCed CPU\RAM\Chipset is too fast for the HDD to catch up?? Thanks for the reply :D	powerover (12121)
1115860	2010-07-05 23:33:00	AFAIK, that RAM voltage should be 2.2 for 800-1066 speed.. Here is the best clocking guide on the planet. Thats Anandtech forums.anandtech.com um...I set my rams on 2.22V, because before OCed, running everything on stock default settings, they won't boot on the rated 2.1V, I have to set them on 2.2V for them to work properly....now considering im OCing them a little bit, shouldn't I give them a little bit more voltage, or am I just wrong and 2.2 is enough?? Thanks thanks for the link, will read through it and do more research :D	powerover (12121)
1115861	2010-07-05 23:37:00	Oh yeah, and your PSU looks a little weak to be overclocking with SLI, I tend to go way overboard with mine, you can see my specs here: New PC (pressf1.pcworld.co.nz) hell, my PC looks, sounds, goes, feels like a little kitty compared to your monstrous lion king.... oh and the link for the pics doesn't work..	powerover (12121)

No. The SATA bus itself can become overclocked, and this results in corruption because the drive is running out of specification and cannot handle such a fast speed. It's not that it has to 'catch up' it's just that it's being pushed faster than it can go. SATA is actually not very tolerant of overclocking. I don't know if this is the problem here, though. Memory corruption etc is different. If a memory module is overclocked too far, or not configured properly, or is faulty - then data passing through it can become corrupted. Sometimes this corruption is not noticed and the corrupt data is then silently written to the disk where it causes problems.	Agent_24 (57)

I did run a memory test, using memtest86 last night. it took aaaaaaages and my memory, using default clock speeds, but 2.2V, passed all tests (I think) without error. about that sata thing...thanks for the info, will do more research on that one :D	powerover (12121)
1115864	2010-07-06 01:36:00	Which did you use, Memtest86 or Memtest86+ ? I only use Memtest86+ myself. When it's finished a pass, it will say "Pass complete, no errors" if everything was fine. If no errors were apparent (in Memtest86+ they are very obvious, they are listed on the screen in red, you can't miss them) then the RAM is probably fine	Agent_24 (57)

1115866	2010-07-06 01:56:00	Couple of points in here that are not entirely correct. Overclocking does not increase the speed of the SATA chipset, the SATA ports are integrated in to the southbridge, and it is not possible to overclock it, it also sits on its own dedicated bus, so even if the PCIe bus was overclocked, it would have no impact on the south bridge at all. If you have a seperate SATA chipset (common) that sits on the PCIe bus the PCIe bus is locked at 100Mhz, this is also not affected by overclocking at all, although some motherboards do allow overclocking the PCIe bus, I have never done it and don't really see the point. What IS affected by overclocking a great deal is the north bridge as it provides a system bus clock (AKA the front side bus, but no longer the case with i7 which is internal now and called the base clock) this is what links the northbridge to the CPU, and the northbridge talks to everything else such as memory (on older systems) the southbridge and the PCIe bus. Intel "chipsets" are awesome for overclocking! my last Asus board had a P45 chipset, and my current one is an X48, but intel chipset, and I don't think you can get any motherboards that aren't intel chipset, you can get boards with nvidia bridge type chipsets that allow greater PCIe speeds but the Northbridge and Southbridge are still intel. And the PSU calcs are all well and good but keep in mind that those calcs are working out your maximum load, you can't base your PSU purchase decision on that figure as only the top quality PSUs can actually output their rated capacity! and even a slightly lesser quality one will have degraded DC quality at close to thier maximum, and clean stable current is very important when overclocking, you should be looking at least a 20% overhead based on those calculators, especially if you upgrade frequently like I do.

I know the version is 3.4 tho. I down loaded the iso and burn it to a cd. boot into it, default setting is use 3.5 to test the ram, but it keeps restarting after about 10s....so changed to 3.4, and it passed all the tests... and when all the tests were done it restarted the test from 0 again, without restarting the pc, so I press ESC to quit. but i clearly saw that errors are at 0.....	powerover (12121)
