w3565 @ 4.0ghz

[neoguyver1]

Hi guys, I just got my w3565 (i7-960) and new mushkin blackline 998776 3 x 4gb.

I settled on leaving DRAM on auto but bumped voltage to 1.66. is reading 8-9-9-25 in CPU-Z. Any advice on timings and voltage for these?

I disabled Hyperthreading for test, which is best?

Also what to do with QPI?

The CV of the CPU is reading 1.296, 24x167 @4ghz.

I was using a Zalman CNPS10X Flex with 2 arctic cooling F12's 3pin set to voltage on a splitter(very quiet).

I was using the "In Place Large FFT's" in Prime 95

Hyper threading throws her into the early 70's.

dude please for the love of god drop that multiplier and put the BCLK up.

Thats a n0000b 4ghz. Mans 4ghz is 200x20

lol yea i am a noob at this will give it a blast, can i ask in a noobish way what is the advantage of dropping multiplier?I do see an increase in temps after 20x200 like serious? voltage was on auto gonna lower it see how goes.

opened the side of the case as she was rising a little as my case fans are barley turning for noise levels.

The 200 BCLK that Tom suggested gives the advantage of being able to run your RAM faster. I remember seeing 2000MHz on his RAM in one of his vids. I think it goes like this for a 133 BCLK: (I got an AMD board w/ diff mutlis, but the same speed options)

1066 = 133 x 8

1333 = 133 x 10

1600 = 133 x 12

1866 = 133 x 14

with a 200 BCLK

1600 = 200 x 8

2000 = 200 x 10

Anything past this point may not be stable, as I have not seen any 2400MHz kits.

2400 = 200 x 12

So what is point of higher multipliers in formats such as Intel's extreme or AMD black editions? I can change the multiplier on my ram also.

Higher multipliers are used to get past Reference clock walls (in intels case bclk walls). Maybe not so true with the newer extreme CPUs but the earlier ones had far lower bclk walls then there non-extreme counterparts. My W3580 has a Bclk wall of 180 for example. Whereas most non-extreme chips will at least get to 215.

Getting higher ram clocks and maintaining your current CPU clocks is also alot easier when you have more multiplier options. Given you have a Xeon I would probably experiment with your ram abit more as Xeons tend to have stronger IMCs.

Good to know (the IMC thing). I forgot to post about BLCK walls. One thing to note is the phenomenon of "BCLK holes." It's when a certain BCLK (ie. 181) fails to post, but increasing the BCLK actually allows you to POST (ie. 185).
