I BLITZed my new retail QX6850 @ 4X5Ghz in the Mini-Cascade

I finally managed to buy a QX6850 here in Portugal , this CPU cost me a fortune - this hobby is becoming really expensive :rolleyes:

For a quick test I mount it in my Mini-Cascade with a Asus BLITZ Formula that I'm testing..

The mini-cascade is not at all quad-optimized (drops to near -60º on load) maybe with some more ethylene may improve a little bit, Ricky said needs new capilar for hold better the 4 cores load.

Here is a photo of the retail box in the mini-cascade:

After a few changes in bios and with not to much voltage here is a 4X4x5 (4 simultaneous Superpi's / in the 4 Cores / @ at 5Ghz) :

I think 4X sub-10 is very possible, the memory timmigs was not optimized, but the the Asus Blitz performance per Mhz ratio seems quite nice in :)


With 1.75v this QX6850 even run Cinebench at 4.900Mhz as you can see:

Next I will find how much is the max speed that can pass 3DMark2006 in the Blitz with the mini-cascade not recalibrate for Quads..


Tomorrow, maybe I will put it on the EVGA 680i to play my favorite game (3Dmakr2001 of course :) ) with the 8800ultra in SLI

:yepp:

4 cores, low voltage and "weak" cooling. Amazing scores and golden chip :D

Looks like you're having fun Pedro, now time to try it on the 3 stager.

These chips are really something else though.

pedro, -60 on speedfan right? and about evap?

great cpu :D

O primeiro de PT
Very good CPU, this cost more then the "average" QX??

Very nice oc Pedro. :clap: Love these QX6850's hitting 5 without LN2.

well if you call 1.74V on a quad low voltage, I'm not sure what you want to see...I say that heat dispersion is already high enough and hard to control.
My Mach I gives up with dual load and 1.7V just as a comparison...

Even it is not quad-optimized I like that mini-cascade pretty much.
It is just the right cooling for some quick tests before spending any money for LN2.

That chip does really well and I enjoy seeing you hitting a nice oc after the other pedro :D

best regards my friend :toast:

very nice

Congrats with the new and good chip and the results,nearly sub 10s 1m SPI with 5ghz is very good. The performance/mhz ratio is very good :D.

Keep pushing it.

another monster CPU :shocked:

Every QX6850 G0 are huge monsters.Does this one costs more then 999$??

Superb..... 5Ghz with only -65....this chip looks like a real dream...Can you tell us the stepping pls?

Thank you (and once more, congrats!)

Spot on :up:

very impressive results. Congratulations ! :toast:
Will your QX feel DICE / LN² ?

Very impressive CPU Pedro! =)
Any plans to use LN2 on it any time soon? :)

Yeah with LN2 this might be a '06 killer chip :D

Great cpu you've there Pedro ;)

:clap: Amazing!

NICE!!!!:up:

hey bro your blitzing anything you can touch.. :D

very nice clocks.. :) you :rocker:

Congratulations Pedro excelent cpu!!

OK, in order to play with 8800ultra's in SLI I have to mount this QX6850 in a Nvidia 680i chipset mobo...

I first try with A0 EVGA 680i with Vcore, Vdrop and Vem moded and no go ..GTL enhacements missing for Quad OC, so better forged non-A1 with QX6850's :(

Then I try with a non moded EVGA 680i revision A1 (D00) with no mods that OC's well but have an horrible Vdrop - 1.8v (bios) - 1.75 (idle) - 1.73 (load)

BTW : Could someone please post a better photo of the VCore and VDroop mods for A1 revision that the one that is here http://www.xtremesystems.org/forums/...d.php?t=154897 ???

Anyway here they are the first results in the mini-cascade.

4 Cores run at 5Ghz

3DMark 2006 run at 4.8 Ghz ..not bad with such high vdrop ;)

http://pedrorocha.planetaclix.pt/QX6...Dmark06Cpu.jpg


With 2 cores (core0 and core3) only in can run my favorite game at more than 5Ghz.

Some 3DMark action later, preferentially after do the Vdroop mod.

I may even run some PCMark05 with Vista, but Fugger's 1st place is unreacheble with this small cascade ;)

Very good:D 5Ghz PI on quad it's good will you also mod the Ultras and use RickY GPU cascades??

Really Nice CPU

really nice cpu there PedroRocha and to run 4 is not easy and then 4 at 5000mhz well nice one good luck and look forward to some good results from this cpu
