4x2GB HyperX Blu 1600

Seeing the Kingston HyperX Blu 4GB for under £20 today I thought i'd grab another pair for my new build soon to make it up to 8GB. From the item description on OcUK it says the sticks run 1600mhz at 1.5v but the Kingston website says that they need 1.65v.

So will I need to drop all 4 down to 1333mhz @ 1.5v to safely overclock a 2500k with them or will the CPU cope with 1.65v as i've seen thats the veeeery top limit of whats considered safe.

Thanks

RAM voltage, speeds and timings play little in the overclocking of a Sandy Bridge chip.

You will probably be able to run the RAM at much lower voltages any way.

Thanks for the quick reply, i've just done a bit more looking around and it looks a lot less of a precise art than I first thought so theres room for a little tweaking at least.

I have these and can confirm that they run 9-9-9-24 @1.5v.

I have these: http://www.overclockers.co.uk/showproduct.php?prodid=MY-094-KS (the grey version, 8Gb) and although they run at 1600 with 1.5V, they haven't been totally stable for me so far. I get weird memtest86 errors (no errors reported, but the screen goes garbled just as it finishes one pass and starts another). I don't know if that's a genuine memory error, but the only way I was able to prevent it from happening was to run at 1.5V, 1333. I'm not particularly worried, as it seems to have speeded the computer up - but that probably just indicates it was having problems at 1600.

@mattbuck - have you tested your sticks with memtest86? I wouldn't be confident running mine at those speeds and voltage.

Actually I take that back. I've just tested with memtest86+ overnight, using XMS profile (1600) @1.5V and there were no errors, and no screen glitches. So I guess the problem I was having was with the version of memtest I was using - another vote for Kingston 1.65V Hyper-X memory being stable at 1.5V (but in my case 9-9-9-27).

Yeah no problems here mate. Just to confirm the actually proper timings are 9-9-9-27 on mine, but my bios had them set at 9-9-9-24 and as there were no problems i left them at that.
