E6700 L638F meets Kayl Dice Tube

Afternoon all,

I only got this chip a few days ago but because I'm familiar with all the walls of my current equipment I've been able to quickly determine how the processor performs. I felt comfortable enough with it to move on from watercooling and onto DICE, some of you might recall I was able to about 4350mhz on water so I was hoping the chip would scale to 4800mhz+ on DICE to leave some headroom for ln2.

Kayl was very correct with a comment he made recently, this core2 chips, scale better with cold than they do volts, once you get to a certain voltage level it starts scaling very slowly. I find up to about 1.65volts you get good increases in speed after that its 100-50mhz or less at a time.

prepping vmods



A layer of clear nail polish over the close components around the socket, then I also cover those areas with the rubber cork tape. I need a vcore mod as 1.7v wont be enough on P5K deluxe, 50K vr resistor gives me in excess of 2v if I need it, but 1.9v will be my maximum today. Once I've mounted the temperature probe to the tube, and the tube to the mobo I'm ready to go!

adding more dice



Benching setup:
E6700 L638F
Asus P5K Deluxe w/ vcore mods
Cellshock PC8000 C4 w/ corsair dominator fans
eVGA fx5500 PCI
OCZ GameXStream 700w
Fans on mosfets and northbridge
Kayl Dice/LN2 Tube

Once the DICE was bubbling away and I had confirmed the bottom of the tube was the normal minus 66-67 celcius I started up my rig and started with 1.5v I was able to achieve the following rough speeds at these voltages.

1.55v @ 4200
1.55v @ 4350
1.60v @ 4450
1.65v @ 4550
1.70v @ 4600
1.75v @ 4650
1.80v @ 4700
1.85v @ 4750
1.90v @ 4800

I think these results show that this probably isn't the best chip at scaling high on low voltages, but it should get me to 5100mhz under LN2 and get me under 10s.

4804mhz validation

So my max validation available was at 4804mhz, my new personal best max clocks for core2duo. Happy with that I moved onto best 1MB PI time. I've been working hard over the past few months at PI optimization but the best I was able to achieve with this chip was 10.922 at 4653.5mhz, ram @ 581mhz 4-4-4-4 5-25-5-10-10-3-7-3-5



I also though I'd have a crack at 32mb PI, I was able to achieve a time of 10m 50s @ 4610.1mhz. Ram clocks were nice @ 576mhz 4-4-4-4 5-25-5-10-13-3-7-3-5 , stupidly enough I hit enter on the PI calculation is done screen before I could get a screenshot, but if you want to doubt the result your welcome to Here is the run before it, at less mhz, less ram speed, similar timings.



These runs were done with optimized windows server 2003, copy-waza, maxmem 496, pagefile 48-92mb, no ramdisk.

Throughout benching the cpu sat between -67 and -57 degrees when benching pi, around -70 idle in windows.

All in all, a reasonable day of benching, In the end I'm glad I ran out of DICE or I would of sat here all night trying to optimize 32MB PI at 4600mhz

Good work... I m really tempted to send you my E6700.. or i will perhaps shoot it myself under Dry pr Ln2... he he

Dude, that first layer of foam is so shoddy heh.
Well done though.

haha yeah it looks preety dodgy in those pics, it seems to do enough though to keep the whole area air tight..

Re: E6700 L638F meets Kayl Dice Tube

you really pushed the CPU well on DICE

what does that CPU do on air or water?

Re: E6700 L638F meets Kayl Dice Tube

dinos i dunno about air i kind of skipped air,

on water it does about 4350 max validation and around 4300 PI stable,

i was hoping for 4800mhz PI stable on DICE but hopefully LN2 will give me what i need, might have another dice session first and try to optimize my 32MB runs and wprime, pifast..

that's a nice CPU

surprised you couldn't go past 4.8 validation on DICE

why did you want to test my one >> that one seems even better as i only managed around 4250 Pi

Re: E6700 L638F meets Kayl Dice Tube

yours scales alot better on lower voltages, i think my cpu is around 5100 - 5140mhz on LN2 I think yours is 5300-5400mhz, depending on how high its fsb wall is...
