@flanker I was testing both BIOS versions on P5E Deluxe a while back and Maximus Formula topped out around ~520 with Wolfdale (E8400) while Rampage Formula BIOS did ~610 with everything else exactly the same (or as similar as possible).

These are quite useful for debugging memory slots. -

Typhoon Thaiphoon Burner should work even unregistered.
the IC is only noted in very few DDR3 kits. Beyond that, 8GB sticks aren't gonna be Rev D anyways since its a 2Gbit ic, so largest sticks containing it (not counting registered memory) are 4GB sticks, like 2666c10 dominators, 2600c10 gskill tridents, 2400c9 tridents and similar.

Not a fun chip to bin for sure, congrats!

I think I've seen that issue before with DFI 775 boards

Memory on Ln2 as well?

I'm intrigued and slightly terrified.

There the 7700K/7740X reign ends...

Thank you for sharing your results
The droop you see should be mostly due to the output sense location which is near C20. It could maybe be improved in a future version.
What would you want to do with a 2-3 phase version?
I've never tested actual current draw, but I recon a 2-3 phase setup could be useful for smaller GPUs, maybe x48 chipsets and x58 VTT rail (never actually checked current draw of that rail, need to test at some point). There are probably more usecases that I can't think off right away.

534 fsb 32M with a 45nm quad on x48, wow. Good run!

currently have 3 dead/damaged rex here.
#1 - dead vcore fujitsu + some conductive thermal paste near NB shorting the nb vrm. Board appears to be working fine again.
#2 - dead vcore fujitsu, vcore shorted to 12V. Found dead mosfet, replaced it + driver + controller, it blew straight up again. with lab psu it goes beyond memory training during post, so I assume with proper epower it should work properly.
#3 - dead vcore fujitsu, vcore not turning on. lots of corrosion. With controller removed + epower it doesn’t attempt going beyond 00. other unnecessary chips have been removed. tried powering SB with lab psu to check current draw, it only draws 15mA at 1.05V which seems very little. Suspicion is dead SB but beyond that no idea.
resistances appear normal on all 3 boards after faulty parts have been removed/fixed.

I'm surprised you got a xeon to OC properly in that thing. Also, try a different GPU/slot maybe?
will try if I can get it working again, today it decided to be dead. Maybe it works again next week who knows.

So maybe a contender! ?
nope, pcie seems to wall too early. need >135 pcie for >300.

Corsair 1800c7 is probably the most available strong D9GT* bin in that case, though still not easy to track down.

Because Hypers tend to shit themselves quite easily, I guess.
Never had a stick die on me, though I’ve had several DOA sticks.
Hypers (MGH-e, avoid MNH-e) ran at sane volts tend to last a long time and should be faster then you can get D9GT. No point handicapping yourself with a weaker IC.

Hyper still easily beats those, why do you insist on using what was best when the platform was released instead of what turned out to be best a couple months later?

I've never ran into that issue, I've ran 2.3V Vdimm with 1.5V VTT without consequences. Also 2.1V vdimm with 1.4V VTT for many hours, with at least a dozen different Chips. I suspect it mostly affects ES Nehalem chips and maybe C0 stepping which I never bothered testing since they tend to be significantly worse then even average D0s. The only source with actual statistics on this I've managed to find seems to confirm this as well. I've heard some people get better stability at a <0.5V delta but never managed confirming this for myself.

another thing of note - avoid mixing pcbs.
the entire day yesterday I was fighting a kit of mine. First, these are the top 4 sticks out of ~20 sticks or so, they are from 3 different kits. I swapped everything (tried 2 boards, 2 PSUs, 6 CPUs, 3 OS), and it just made no sense at all. Each stick on its own is capable of 1100+ 7-7-6 32M. Booting 1100+ and running waza with any 3 of the 4 sticks is also easy. However, they do not pass 32M under any circumstances at 1050+ with decent timings.
Turns out - corsair is using several different PCBs for their hyper based sticks. I have 2 50-00187A and 2 50-00218A in this kit.
Looking back, the earliest sticks with the 50-00218A pcb I’ve seen are 10122374; I’ve also seen it on 10122507.

3:5 is a broken divider, 2:3 real, so 645*3/2 = 967 real which is still quite nice of course. Lots of 775 scores with misleading memory frequency, but some boards just run best at this divider so can't do much about it either way. This also means that every couple months someone has to sift through the DDR2 frequency rankings to check if any subs were made with the broken divider.
Great chip you have there!
