~~~~~DEAL OF THE CENTURY MK2 - 4GB 1600MHz CAS8 Kit ONLY £25.99 Delivered (PRE-ORDER PRICE ONLY)!!!~

have a look on the SPD tab of CPUZ, should tell you all the info you need for the 1600MHz settings.

only goes up to 1333mhz, thats whe whole thing, i think this ram is actually some other ram, which ocz has decided to re-sell under a different name and different settings than it was manufactured for.

therefore any motherboard, will only detect the old settings, which are slow and loose.

i want the fast and tight timings, but they only four values, when you really need all of them.

What motherboard have you got? Mine is a gigabyte ga-p55-usb3. It has an overclocking/tweaking menu within the bios which has plenty of options for me to choose from.
I have been reading up on overclocking this specific ram and what other timings people have been using. Ive read that folk have been running these at 7-8-7-24 and 6-8-6-20

I tried the above and have been fiddling around with different voltage settings that people recommended to try. Also changed the frequency and adjusted speed to around 1670-1690mhz. I did benchmark tests with Hyper PI (to test the PC performance) and Sandra Pro Home (mem bandwidth test)
Overclocking the memory gave me more memory bandwidth etc but the PC performance was slower. Therefore I came to the conclusion that in order to run the memory at those speeds and timings, then you would have to overclock the CPU as well to benefit fully from it.
I would overclock the cpu but its only got a stock cooler on at the moment and it is absolutely rubbish as its already running hot(60-70c) so therefore I havent overclocked the cpu.

I have kept my settings to 8-8-8-24 T1 @1600Mhz 1.64v and it runs fine.

If anyone else has any better settings or know more then please do let us know

My RMA'd stick has been tested and a replacement set has been posted today. I only sent them on Monday, so OcUk turnaround is PDQ.

asus p8p67 standard

i got it running at 1600mhz, 9-9-9-24 and 2t @ 1.5v

theres lots of stuff saying not to go over 1.5v on sandybridge or else it will shorten the cpu's life.

if you check on the official ocz forums, they suggest running 1600mhz 8-8-8-24 and 2t with 1.65v

for the sake of .15v, i dont think it will be worth moving from 9-9-9 to 8-8-8.


why do you have it set to 1t? is it okay to do so?

edit: a lot of people saying 1t for 2 mem sticks and 2t for 4 mem sticks, therefore since i have 4 sticks of this stuff, ill stick with 2t.

seems fine as it is, what performance gain would i see at 8-8-8 as opposed to my 9-9-9? if 1.65v is fine to run on sandy

I read it about it on other forums and as I said that those who do go further and increase it more than 8-8-8-24 should also increase the cpu clock speed as well otherwise you will see the performance of the cpu drop on your benchmark tests.

As for the T1 and T2 options, I did have it set to T2 before but then I came accross other posts where people have been using T1 and this short guide also mentions some info about it:
http://www.hardwaresecrets.com/article/Memory-Overclocking/152/6

Check the last line on the page " If your motherboard has the CMD timing option (which is optional), configure it as "T1", since as "T2" the memory performance is lower."

If more people can shed light on this as to wether we should do it just for 2 memory sticks or 4 sticks or if it doesn't matter how many memory sticks there are then please do let us know.
