ES Xeon Discussion

[RolloZ170]

Have you managed to downgrade to that old bios? I thought it was not possible to downgrade from a 2.X bios to 1.X.

P60 Firmware Family - Revision History:

WARNING: AMT must be enabled before downgrading from any 2.XX BIOS version to any 1.XX BIOS version. This requirement is due to a ME Firmware mechanism incompatibility between these different major BIOS versions. After a successful BIOS downgrade AMT can be disabled.

Affordable ES+MB DP bundle listings with LGA4677 Sapphire Rapids started to appear on e-bay like itm 385686986603 : GigaByte MS73 + 2x 20Core ES QYFT CPU

the seller wants $1399 usd for the bare MS73 board, makes $400 usd for 2x QYFT.
$200 is pretty much, you can get QYFQ/QYFP ES2 D0 48 Core for $200 usd.

 

[sam55todd]

Yes, thank you, I saw bare-CPU options at that price, but for now trying to avoid ES with D-stepping because of my X13DEI Supermicro issues with those (since vendor decided not to implement retail bios support for it).
Previous post was just to point--out what it's gradually gaining a broader availability on a market.

Anybody have a guess what these Sapphire Rapids OPNs might mean in terms of cores/clocks and compatibility?

QY36
Q0KG

For the first one google says C2 56core but still a QYnn, which is most compatible opn from what I've red so far, so sounds strange to me.
As for the second one, google is absolutely silent ...

QY36 1.7 Ghz 105.0MB 56C 350W C2 <- you need Debug BIOS. this stepping in not supported by Intel RC anymore.
Q0KS 2.0 Ghz 36C 300W stepping E0
Q0KG 2.0 Ghz 52C 350W, step E0
E0 currently supported by all stock BIOS (SM,Tyan, GB)

In case if anyone still follows self-torture path (or are lucky to have Gigabyte MB with right BIOS) - another $250 cheap D0 stepping LGA4677 alternative Xeon ES QYFU 1.8 Ghz/48c surfaced on ebay space with item 385713079210 from China.
Multiple prod items start appearing over the recent days too but still way too high above Intel' guide price.

 

[RolloZ170]

Xeon ES QYFU 1.8 Ghz/48c

they sell it as 8561v so i expect it works only as single socket.

JFYI - despite the fact that Gigabyte says MS73-HB1 has "Gen4" M2 slots, it actually trains at PCIe 5.0 speeds, and I get this with Crucial T700 SSDs.

Just please make sure SSDs are >actively cooled< (with a fan, not just the heatsink) otherwise they will go in throttlefest mode.

 

[RolloZ170]

FYI - despite the fact that Gigabyte says MS73-HB1 has "Gen4" M2 slots

facts in manuals ?
copy/paste form MD72-HBx
edit: maybe the M.2 slost are not validated for PCIe5.0 or not properly wired for that and have to many PCIe transfer errors in 5.0 speeds.

 

[psyq321]

Not only in manuals, on my mobo there were small "Gen4" stickers on both M2 slots, which scared me.

I also guess they did not validate / some tests failed - but thankfully, it works.

Now, about those 3x UPIs - I am getting my waterblocks today so I can power on the second CPU. But I suppose that is probably true. Supermicro X13DAI/DEI have 4 UPIs between CPUs, but suffer from different tradeoffs (some x8 PCIe slots). I guess E-ATX format is at its limits here.

I have two QJWD Xeon (AWS-1100v4 or 2676v4?) but it is not working in HP Z440 (5 beeps and red led flash) and Dell T5810 (no beep just a blank screen). Or my workstations simply not work with v4 cpus?
Do i need older microcode or newer bios?

 

[RolloZ170]

if not the QJWD ( AWS-1100v4 ) does not work.

Do i need older microcode or newer bios?

nothing special normal V4 microcode, 145W TDP

 

[masterdeejay]

The TDP is not the problem, i use 160w 2687wv3 in one of my dell T5810 (custom all core hack unlocked bios + Rebar support) HP Z440 also works with 145w 2697v3.
I think i removed the microcode in the Dell when i added the turbo hack.
I am trying to update the Z440 bios.

 

[RolloZ170]

the AWS-1100v4 may have the OEM TDC=199A like the E5-2696v4, some motherboards don't support this.

 

[masterdeejay]

Hp z440 latest 2023 bios. All keyboard led blink once but not starting, i got 6 beeps.

It is working in asrock x99 as AWS-1100v4 but lost some pcie lanes (nvme not working). And there is something with the video card support, only a GT240 works with this, Gtx580 not working (the gtx580 and the nvme works with 2699v3 on this motherboard.


Is there a guide for the TDC mod? I can edit the bios if needed.

 

[masterdeejay]

It works, but only with 1x pcie slot video card from trash. (7300gt)
Both cpu have only a few pcie lanes.

 

[RolloZ170]

TDC is compared with the icc_max of VRM controller by intel ME (PCH firmware)
so far nobody changed anything in intel ME code., the only way is to change the icc_max.

 

[masterdeejay]

Its start now.
TDC wasnt the issue (it is 176A) but the pcie lanes. Only the 2.0 pch lanes are working. But i dont think both cpu comes with dead pcie lanes so it is some compatibilty issue.

it is ES/QS and OEM but should work
