Overclocking with or without HyperThreading: Wut?

By this, what do you mean? Stuff like Speedstep etc?

My P6X58D-E board won't arrive until next week so I've not had a chance to look around in the BIOS as yet but will more than likely resurrect this thread in a few days time to pop a few more questions. :D
 
A bit stumped

Right - Finally managed to put this system together so I'm back to pester you folks 'in the know' with a few questions. First one up is DRAM timings and voltages. I'm running Corsair XMS3 1600 sticks, 3 of 2Gb each, all sat in the blue slots on the mobo. The timings on these are 7-7-7-20 at 1.65v. I've had a shifty in the BIOS to see if I could quickly change these before I start tweaking anything else but I'm a bit confused as to what values to change to 7-7-7-20. I'm not a complete idiot (I hope) but the DRAM options in this BIOS on this board look vastly more complex than my old P5K. There seem to be a lot more options in there at first glance. So what do I basically need to change at this point to get the XMS3 running at 7-7-7-20 @ 1.65v?

Ta. :)
 
Under the ram timings menu, you just need to change the first four in the list to those numbers, rest are ok on auto. Dram voltage, set to 1.65, if 1.65 isn't showing set 1.66 as this is ok. Some boards only go up in two's, ie 1.64-1.66.
 
Roger that, I'll go and do that just now. What about DRAM Frequency? Set to 1600 I assume? This is what CPU-Z is saying its all sat at just now on Auto:-

8x multi or whatever multi gives you 1600mhz or close enough to it

system memory multiplier (might be labelled differently on asus)
 
Yep, on Asus boards its a drop down menu of frequency's you select from. Pick the one closest to 1600, though iirc 1600 should be available.
 
Okeydoke, timings changed to 7-7-7-20. Do these screens of CPU-Z look ok? I tried changing the DRAM Bus voltage and it threw a warning at me, is it ok to go ahead and change it to 1.65v anyway? As you can see from the second CPU-Z screenshot on Auto its giving 1.50v to three of the RAM sticks and 1.65v to the last one. Leave it at that or manually adjust to 1.65v? Last image shows the warning that popped up in the BIOS:-

that's just the rated voltages the ram can support,yh 1.65v is fine,and your running 1600mhz ram speed now 800 x2 = 1600
 
Cool. I increased the BCLK to 150 (other than the DRAM timings and freq that's the only thing I've changed within the BIOS) and it's now sitting at 3148.14MHz. But it seems to have set the DRAM frequency down a little from what it was @801.3 MHz to 749.9MHz :-

yeah that's right,ram freq is linked to the bclk so if you raise/lower it it will raise/lower the ram speed

EDIT: 150 bclk x 10x memory multi = 1500mhz ram speed and so on

Ta.

In that case, I'll bung it up to 160, I assume that as well as upping the CPU speed that doing so will bring the RAM speed back up to 1600? I've ran Prime for an hour and a half with no issues at the BCLK of 150 so 160 is worth a shot I reckon. Ideally I'm after a mild overclock with no additional voltage increase, certainly at this stage of the game anyway. :cool:
 
Give it a shot, 21x 160 bclk = 3.36 ghz, using the 10x ram multiplier will be 1600mhz, (10x bclk of 160). How are your temps holding up under stress testing? Iirc my old 920 went all the way to 3.6ghz on 1.2v, anything after that needed quite signifigant increases.
