Let's see how stock temps are... as we can see stock VID = 1.275v and AUTO vcore in bios confirms it at 1.248v real vcore when AUTO vcore is set. This is same VID as my Q6600 B3 ES (http://fileshosts.com/intel/Asus/P5K_Deluxe/results/Nautilus500/Q6600_B3/team/6400c3/8x/5_6/490-588_4449_3-30-338_1.6375-x0.63-1.5-2.55-1.4-1.7-0.67-1.2/wprime_32m_1024m.png) cpu as well which managed on water cooling to be Wprime 32M + 1024M passable @3920Mhz at 1.616v (http://fileshosts.com/intel/Asus/P5K_Deluxe/results/Nautilus500/Q6600_B3/team/6400c3/8x/5_6/490-588_4449_3-30-338_1.6375-x0.63-1.5-2.55-1.4-1.7-0.67-1.2/wprime_32m_1024m.png) in <14C ambients.

This cpu is a bit weird i must say temp wise is slightly cooler under small ffts quad prime95 load clock/vcore for clock/vcore than my Q6600 B3 ES but prime95 wise isn't as good as my Q6600 B3 ES but wprime 1024M is better on Xeon X3230.

Basically, since Xeon X3230 ES meeds more vcore for Prime95 small ffts than Q6600 B3 ES, the final load temps are about the same 62-66C on same water cooling - Swiftech G4 Storm/Thermochill 120.3/MCP655.

i.e.

Prime95

Xeon 3230 ES @3600Mhz at 1.48-1.49v (under small ffts load vcore)
Q6600 B3 ES @3600Mhz at 1.44-1.45v (under small ffts load vcore)

Wprime 1024M

Xeon 3230 ES @3600Mhz at 1.376v
Q6600 B3 ES @3600Mhz at 1.45v

Systool Quad 16M

Xeon 3230 ES @3600Mhz at 1.416-1.45v
Q6600 B3 ES @3600Mhz at 1.45v


Looks like a good benching cpu this X3230.

[eva2000]

Xeon X3230 G0 @3600Mhz at 1.48-1.49v

Now at my goal overclock of 3600Mhz which took 1.48-1.49v to get there.

Ended up same load temps as Q6600 B3 ES due to needing 0.03v more vcore on X3230 G0 ES.

I have a D-Tek Fuzion water block I plan to swap in and swap out my Swiftech G4 Storm since D-Tek Fuzion is meant to be able to drop load temps by up to 10C compared to the Storm as per http://www.xtremesystems.org/forums/showthread.php?t=136703

When you mount your D-Tek FuZion, your temps will be a TON BETTER! Nice CPU Eva, I envy you and your work

[JAG87]

I have the same cpu eva. Identical, same week same batch. But my VID is lower, 1.2625!!!!!!!!!!! :woot:

2.66G with 1.22v idle real after droop, and 1.18 load real after droop (while doing small prime). and now the fun part. with a stock e6600 heatsink... :ROTF:

my average core temps are 45 idle, 65 load, with the little intel aluminum circle :rolleyes:, but my apogee gtx should be coming tomorrow or friday. the rest of my loop is empty and waiting for the block.

I will post my results in your thread since its the same chip essentially... wish me luck!!!

[PcCI2iminal]

great post as always :)

have you tried the max FSB?

ps. i like that Blitz :D

[shimmishim]

very nice!

i also ordered a dtek fuzion. i hear they are very good with quads.

and 3900 benchable is pretty darn good for that chip

Yup sure is... this Xeon X3230 has some potential with wPrime 32M + 1024M @4000Mhz at 1.64v and max cpuz validation also at 1.64v of 4112Mhz!

how the bandwidth affect the scores on wprime 32m?
i had a similar score @ 4ghz ( 10 x 400) , 1:1 cas4-4-4-8 PL->6

It seems lately the ES's have been way out performing retail. Great Chip though eva2000. Great review. I'd hold on to that one!:clap: :yepp: :yepp: :woot:

my dont go on air above 3900mhz, once I've seen 4ghz and validation file was corrupt, but your cpu need more voltages @ 3.6G hmm, interesting..

i had a similar score @ 4ghz ( 10 x 400) , 1:1 cas4-4-4-8 PL->6there is an effect.. but v1.53 wprime is a bit slower than previous versions due to the added anti-cheat measures etc in v1.53 wprime

:woot: so far DDR3 is fun to play with but not sure whether the Blitz Extreme might be holding back my max FSB of my cpus as my P5K Deluxe has clocked all my cpus at least 10-20FSB higher than Blitz Extreme but bios is still early 0601 version and 0702/0801 didn't change much for max FSB.

sweet what waterblock/loop setup is it ?

interesting the FSB is varying so much we have between 450-480FSB and mine on Blitz Extreme is 415FSB.. swapping cpu into another board now to see how it goes.

In terms of delta load temps, seems to be about right in terms of water cooling where DIY setup of Swiftech G4 Storm runs about 7.85C cooler under load and 3.85C cooler idle (looking at average load to room delta temps).

Repeated same overclock of 3600Mhz but this time on Asus Blitz Formula instead of Asus Blitz Extreme but at 9x400FSB instead of 10x360FSB at same vcore 1.488v idle / 1.472 under load.

Seems even on Asus Blitz Formula this Xeon X3230 G0 ES has a low FSB wall of around 416FSB - whether it's due to bios/board or cpu itself not 100&#37; sure. Still for water cooling this Xeon X3230 G0 ES is a ripper, how about quad instances of Super Pi 32M @3950Mhz - 10x395FSB!

Bloody awesome I'd say :D

[shimmishim]

wow, quad 32M at 3.95!

what voltage was that at?

also, have you tried cpu-z 1.40.8? it should show the voltage correctly now.

[eva2000]

those cpuz windows are 1.40.8 and vcore not reporting correctly.. 1.40.8 can't even save the cpuz validation file properly hence i used 1.40.5 :)

1.65v bios set = 1.616v windows

I have a Xeon X3230 G0 ES too. FSB wall at 450. maybe a little higher but can't reach 460 at 1.55 CPU Vcore. :mad:

[eva2000]

wonder if it's the bioses aren't fully supporting Xeon based G0s ??

I thought the same. if i put the fsb further than 360*10, it is always restarting after 1 minute Primeing! CPU Vcore doesn't matter.

[jugeen]

it's just a valid http://valid.x86-secret.com/show_oc.php?id=225238

[eva2000]

hmmm could be the motherboard/bios limiting FSB why ?

Has anybody still overclocking Quadcore 65 nm Xeons?

You point me to a thread which would be better for X3210 discussion?

This chip has 1.2125 VID

There is 3500 Mhz

Next 3600 Mhz, I hope I don't need to up the voltage too much, I'll try with this Vcore at first, then 1-2 notches up.
