I finally tested the Cellchocks on a decent board. My Blitz Extreme is somewhat not really working with high memory speed for whatever reason. I used a P5K3 Deluxe this time and got way better results

I will post pics later, don't have the time right now. I already posted in a German forum, but the screenshots should speak for themselves. The voltage used is written above the pictures.

Interesting might have to unpack my P5K3 Deluxe and swap out my Blitz Extreme then hehe

How much of a difference on P5K3 Deluxe vs Blitz Extreme ?

Nice! Are they the blue or the black? With the P5K3 my blacks are good for 800 7-6-5-18 1T at 1.65v (black slots). Could you see what freq you get with same voltage and timings? It will be a few days more before I can do more extensive tests, so I'm curious

Edit: hmmm, just ran a 32m with 860 7-6-5-18 1T at 1.75v. These are looking teh sexy.

[Fr3ak]

George, the P5K3 made the hell of a change for me
With the Extreme I needed a vdimm of 2.24V and a MCH voltage of 1.7V to be 1M stable at 900 MHz 8-7-6-21-2T. With the P5K3 I needed 1.4V VMCH and 1.7V to be dual 32M stable at 900 MHz and the same timings.

I also have the black sticks (well, I had ). I used the black slots, cos on P35 Asus boards (the DDR2 ones too) I was able to clock the memory higher using the black slots.

[eva2000]

Interesting indeed wonder if extreme has tighter MCH latencies than P5K3 hence the difference in MCH voltage needed ?

[saaya]

i think that particular blitz was crap
it was probably an older chipset and hence didnt clock very well...
if you ever get the time to remove that heatpipe madness and spot the nb revision let me know olli

btw, did you use the same cpu on both boards?

[eva2000]

Yeah same cpu on both.. blitz extreme chipset numbers

thanks george, and thanks bill, looks like your eye surgery was well worth it

im leaving to yet another ln2 party for the weekend ^^
im taking a p5k3 with me and will check the stepping this weekend.
i compared 3 boards today and yesterday, interesting...

theres a difference of 50mhz between the best and the worst in regards to max clockspeed. same cpu, same bios, same settings.
theres something else that confused me.

remember the old board i always mentioned that only did 1825 max dc stable?
its one of the first retail p5k3... well now it does 1900+...
i switched the cpu and wham, suddenly it runs much better.

the weird thing is, before it was running with a 6600 that could run a high fsb.
now its running a 6750... im sure i checked the fsb stability of the 6600 by using the same fsb or higher with a different mem divider. and it was stable... so i assumed that fsb was stable... but for some reason the 6600 was not stable at the same fsb when i used the 1:2 mem divider.

and the difference between the dividers must be huge, because with the other divider i could run an fsb of 500 easily and it was stable.
with the 1:2 divider i was limited to 1825, which is 455fsb.

could this be correct?
a max fsb difference between memory dividers?
and not a small one but a whooping 50mhz?
im puzzled... ill see if i can reproduce this with the 6600.
or could it be some registers changing once you set a high mem clock?
so once you set a memspeed of 1800+ the chipset/board relaxes some timings or changes something automatically to make a higher fsb stable?
and for some reason this only helps with 1333fsb cpus and not at all or not so well with 1066cpus?
reminds me of the l12 bridge thing from socket a

people could push their nf2 boards to higher fsbs with the bridge mods... its just weird this time that the memory controller is limiting that much.
but in general thats very characteristically for p35 ddr3 in my experience so far, the chipset is very limited by the ddr3 mem controller.
we can reach a notably lower max fsb with p35 ddr3 compared to p35 ddr2, which i think its the ddr3 mem controller limiting.

maybe we should compare the registers with p35 ddr3 and p35 ddr3, maybe on a hybrid board ideally so only the registers important for ddr2 and ddr3 operations change. that way we could maybe find a trick to get the same high fsbs on p35 with ddr3 as with ddr2...

Yeah i suspected the divider might play apart in it on an ealier blitz extreme bios i couldn't get stable using 3:5 divider at known stable cpu clock speed... swapped to 1:2 divider and was stable.

Guess also depends on the NB strap set as some straps offer the same divider.

Well, a difference between dividers ( max clock speed dependency on divider ) is there ( for sure ).
But I don't remember spotting ( well, didn't tried hard almost at all ) any difference in mem clocking with different CPUs.
But I think it's time to try some CPUs with the same board + settings to see if I can reproduce your findings [ the more you test, the more things you need to test ]

[Kamel]

Saaya, i told u p35 was not so good with E6600, better with new stepping CPU such as 6420, 6750, 6850....

So now it's confirmed... i don't know why but E6600 is not loved by P35.. maybe some bios matter in recognizing the cpu step...who knows?

[Fr3ak]

I used a E6600ES on the Blitz and a E6750ES on the P5K3. I wonder if that might have to do with it? I tested both CPUs for max stable FSB. The E6600 does 525 MHz and the E6750 510 MHz.

[saaya]

I might have overlooked the strap setting and that could have caused the difference...

i think it was the strap, not 100% sure tho...

Kam

you had similar problems right?
did you try different straps for the 6600?

i hope i didnt kill that blitz man, im really sorry if i did
i keep thinking about it and maybe one of the smd caps on the nb package ripped off when the nb heatsink came off? other than that... no clue...

when i first booted it the fans were spinning fast, then rebooted and fans were slow, so the board still seems to be working somewhat as it apparently went to defaults after the initial boot didnt work.

does anybody know what a debug card error code of D4 "uncompressed data fault" or something like that means? Are there any tricks on how to reflash the bios? i booted with the mobo cd in the dvd drive and hoped it would load the bios but it didnt even start to read the sata dvd drive...

Btw, the stepping of the NB on that blitz board is

LE82P35
SLA9R
L717A231

same as your eva, right?

EDIT:
L715A337
vs
L717A231

15A vs 17A and 337 vs 231 does anybody know how to read intel chipset steppings?
I think the latter is the datecode since freaks board is older than yours eva, at least i think so...

[eva2000]

i think it's like cpus L715 and L717 = week 15 and 17, 2007 ???

I've swapped to P5K3 Deluxe and much better FSB/MEM clocker than my Blitz Extreme!

[Fr3ak]

So its no coincidence. A modded P5K3 would be better for benching I guess than the Extreme. Apart from the voltage options the Extreme doesnt offer any more features. The crosslink chip is, well, not that great too.

How much better is the P5K3 over your Extreme, George?

[hipro5]

It's ALL about the chipset P35 - they are like the CPUs - Best, better, medium, bad - ......My second Extreme does a bit worse than my first one as for getting OVER 1000MHz the rams.....

[eva2000]

For my E6600 L709A958 difference in max FSB

Blitz Extreme = 485FSB max
P5K3 Deluxe = 530FSB max and 535FSB bootable but hangs in memtest86.

[Fr3ak]

Same voltages being used?

Thats quite a big difference.... Almost like using a quadcore instead of a dual.

[saaya]

wow, thats a huge difference!
so eva, your board is older than freaks then... do you have it for a long time already? you must have a bad blitz too then...

hipro, did you check what nb stepping your p35 is?
eva, can you check on your p5k3?

its strange that there seem to be way more blitz boards with bad nbs than p5k3s... or maybe thats just our perception since most p5k3 users dont push their boards that hard while EVERY blitz owner pushes the board to the max?

i have several p5k3 boards here, some with made in china pcb and some with made in taiwan pcb. ill check if theres a trend of one being better than the other.
