I'd generally avoid 6180 SE chips, getting them to run at 230 required hand-picked chips.
OTOH, tjmagneto's "random" set of 6176 SE chips runs at 230 with no hassle whatsoever.
DooKey,Where is the option to cap NB to 2000? I'm not seeing it in the advanced options.
Maybe it's posted and I just missed it, is there and advantage to of OCNG5 over OCNG4 on quad-socket boards with 61XX series CPUs?
I took a little break off the forum, sorry. In case you still have the board, it should be under advanced northbridge options. If you don't see it, your configuration utility may be outdated.
Go about installing ocng-utils-5 or, for best experience, upgrade everything to 5.2 (http://area51dev.blogspot.com/p/ocng5-installation.html).
Given it's fairly mature project it's as active as its usersIs this tread/project still active?
Check vendor's page. The difference is SAS controller which is not present in the iF board.Was thinking about building a system with a SuperMicro H8QGL-6F or H8QGL-iF (what is the difference between these two?) motherboard and possibly four Opteron 6276 processors.
6300 series are easier to OC and (clock-for-clock) draw less power than 6200 series so they are a better experience.What about 6200 vs 6300 on performance and overclock?
I don't understand the question. You'll need to be more specific.For example, Four 16 core 6200 series Opteron vs Four 12 core 6300 series Opteron?
SE processors require extra care (wrt cooling) so you need to know what you're doing when dealing with them.Looking over this thread, it seems that is best to avoid the SE (140w) processors?
I don't understand the question. You'll need to be more specificAnd what about Retail vs Engineering Samples?
All LN4F boards are currently not supported.anyone try this on the h8qg7+-ln4f?
To elaborate on explanation few posts back -- if you have such board and can spare some
time to examine it (per my instructions) and test the firmware, then supporting LN4F boards
(including H8QG7) should be possible.
Porting the changes is relatively simple and low-risk process. If something goes wrong
(firmware doesn't boot -- unlikely scenario) you will experience downtime as I'll need to ship
you a (non-invasive) recovery tool.
The benefit for you is early access to the firmware
W/retail chips it would allow you to do both or either (at your discretion) of:
1. Forcing all-core turbo (P-state Pb1)
2. Overclocking by means of reference clock (aka BCLK in intel nomenclature)
EDIT: for instance, here are retail CPUs with 20% OC: http://hwbot.org/submission/2921243_tiborrr_hwbot_prime_4x_opteron_6344_12414.34_pps
I have no experience with H80s but if they're as good as Hyper 212+ or 120mm Noctuas,that's awesome news.
think I could get away with corsair h80s AIO coolers or would I need a custom loop? I'm most interested in just the turbo fixing unless I can fix the pci clock rates to 100mhz independent of the memory when doing bclk bumps.
speaking out loud: I would need a 1k+ psu and new cooling for sure.
I have no experience with H80s but if they're as good as Hyper 212+ or 120mm Noctuas,
you should be just fine. All my 4Ps only ran on air. Grandpa ran a 1000W+ (AC) setup
on air as well. Custom loop definitely is not a requirement.
PCI-E clock is completely decoupled from reference clock. No issue there.
PSU choice will depend on your chips, add-in cards and amount of OC...
W/o add-in cards, 850W (DC) is fine unless you're planning to go nuts on OC (go beyond
3 GHz w/6200 series or 3.2 GHz w/6300 series).
3ghz would be all that I would be targeting. Heck 2.8 would be nice.
I'll bite. A few posts earlier I think you alluded to being able to go back to a stock bios should things get hairy.
I'll offer my setup as a test rig.
@[Ion] and @gigatexal, tear is the man and you guys are in good hands. He's done some amazing things over the years for the DC overclocking community and I continue to be impressed with his skill.
picked up a 1300 psu - going to read up on how to get this thing flashed and go to town
Most excellent!It's an EVGA gold rated 1300 G2.
Got my G34s at 3ghz with a reflock @ 231.
i have a 2 140mm fans blowing air on top of the HSFs onto the board and another 120 blowing air onto the board on the other side. i'll look into buying copper sinks for the vrms too
cpu-z validation for 3.2 ghz at 245

I think air should be enough. Incidentally, catastrophic VRM failures have been reported with
sinked boards, too. While sinking theoretically shouldn't have contributed to failures, personally,
I'm wary of throwing sinks at VRM components.
My most heat-generating system was pulling 900W AC (~760W DC) and ran continuously
for many months (air, no sinks).
Perhaps other folks could share their experiences as well.
