Overclocking my RAM need some answers :)

Well after finding out that XMP will pretty much destroy my nice 4Ghz CPU overclock i've decided to manually OC the speeds. Now i've never overclocked my ram before and I need some questions answering.

Firstly lets get the story out of the way. I had 3GB of some lovely OCZ TRIPLE CHANNEL memory clocked at 1866Mhz (Factory OC) with voltage of 1.65v and a 9-9-9-28 Latency.

I just bought some new ram again Triple Channel OCZ kit this time its 1600Mhz but has the same low voltage at 1.65v but the lantency is 9-9-9-24 instead of 28.

(Here are the links)(ADMIN READ THIS: Please dont delete my old ram link as it has been discontinued and this was the only site I could find the specs of it).

OLD RAM: http://www.lambda-tek.com/componentshop/index.pl?origin=gbase20.2&prodID=B208048

NEW RAM: https://www.overclockers.co.uk/showproduct.php?prodid=MY-179-OC

The best Bit:
Ok so here are the questions I'd like answering.

1. Should I OC with both sets of ram in the sockets or just oc the new ram to the same speeds as the old ram before inserting the old ram into the mobo?

2. will I need to change the latency from 9-9-9-24 to 9-9-9-28?

3. Will I need to boost the voltage of the new ram or will it be safe just tweaking the speeds without a voltage boost?

thanks for reading

I'd remove that link. Just copy the ram specs from that site into this thread. That easy.

Hey man. Overclocking X58 with six sticks of ram is relatively hard going, hope you like tweaking.

Your options for ram frequency are six times or eight times your bsck. The other aspect is timings, where lower is better. In practice on the X58 system neither frequency nor timings make much difference to performance relative to the cpu frequency, so I personally put a lot more effort into the cpu overclocking.

The approach I took was to take 4ghz stable settings, change bsck to 150. Increase qpi to 1.3V if it's currently lower than that, otherwise leave it as it is. Ram frequency to 150 times 6, timings to 9-9-9-27. Turn it off, install the new ram, then turn it back on, and it *should* be stable. Test to verify.

I'd then overclock the processor, trying to get it back to 4ghz. If you like, you can go for 150 times 8 for the ram and try this. I cant personally get 4ghz on the processor and 1600mhz ram stable but others have managed it so you may have more luck.

Only once happy with the processor speed, and stable, then try tightening the ram timings. It's a long and dull read, but you may gain something from this. I've pretty much given up on overclocking, it's at 4ghz cpu, 1200mhz cas6 until I find myself with a spare week.
