still running my 1680v2 @4.5 undervolted on P9X79-WS.. currently looking at options for 128GB RAM. Besides newer arch power efficiency or $1000+ massive multi-core monsters I don't see a reason to upgrade tbh. This 12yo system is super fast with a modded bios to allow booting a 970 NVMe drive
It's not going to be easy for you to upgrade to 128gb ram with your p9x79 ws. That board doesn't accept rdimm. Most 16gb ddr3 that's easy and cheap to get are ecc rdimm. 16gb udimm are rare and not cheap. I ordered that same board on ebay and promptly returned it for that reason and keep the p9x79 deluxe since at least that board was cheaper and have wifi, but i still dont like it since it doesn't accept rdimm.

I believe it does. Most Asrock boards support it. I think the Asus WS might also
I tried a 16GB RDIMM once and no post. It does support ecc udimms. I have two 16gb ddr3l udimms in my laptop that I'm going to toss in adapters to test out.

You should remove the W5580,W5590 from the unlocked list. False reports in articles, and misleading CPUZ caused the rumors. Someone even tested an ES chip at TPU and it was locked. I can't find anyone who can confirm an unlocked example.
So far we've found no examples of unlocked 2xCPU Xeons except the LGA771 QX9775.
EVGA Classified SR2 seems to be the only unlocked MB for the 2x CPU Xeon 5500/5520 chipset platform.

I have someone at TPU Throttlestop Overclocking thread trying an E5-1620 and getting no overclock. is there a BIOS or firmware version involved in unlocking these? I remember some conversations about Intel trying to "fix" the unlocked CPU issue.

I think a partial unlock to 43x is what's expected.

So you are saying that this CPU-Z validation is fake? Intel Xeon W5580 @ 5612.23 MHz - CPU-Z VALIDATOR
It shows as D0 stepping (which is the production stepping of this CPU) and an multiplier of 42.

Unclewebb the developer of Throttlestop tested an W5580 and found it locked and another user totalfreq tested a W5590 ES and found it locked also. Those CPUZ validations are one of the reasons we tested them. Maybe W3580 being mis identified? IDK but we're finding no dual CPU Xeons unlocked. (except of course the Skulltrail lga771 QX9775). Whether it's fake or not I can't say. Someone may have found a way to unlock them but they're not unlocked as is. I can't find any identifiable user who says they've run these unlocked. Maybe the CPUID is being spoofed.

QX9775 isn't a xeon, it's a core 2 extreme.

I presume this is the cpuz validation we are talking about? Intel Xeon W5580 @ 5612.23 MHz - CPU-Z VALIDATOR

Cpuz can sometimes misidentify a chip in the "name" section, but the "specification" part is from the chip and the board's bios. so the chip is most definitely a w5580, but i think the validation is glitched. there have been glitched validations like this before (Intel Core 2 Duo E8200 @ 8943.13 MHz - CPU-Z VALIDATOR) but i haven't yet seen one that misreports the multi.

QX9775 may not be "called" a Xeon but it is the only unlocked Dual CPU processor. It's LGA771 which is a dual CPU Xeon platform.
It's an unlocked X5482
List of LGA 771 & 775 CPUs + Current Prices
A couple people have tried the W5580/90 and found them to be locked including an ES.
What's going on at CPUZ IDK, but those suspicious validations always seem to be the fastest overclocks there, and the only one with a raised multiplier. 5.61GHz on 1.216V. is qestionable also. But I think I know how that's done.
I'm the ome who suggested putting it on the list based in part on that validation. Testing has shown otherwise.

Thanks for that.
Here's another unlocked phantom CPU @ CPUZ
X5687 running 56x133
Intel Xeon @ 7482.97 MHz - CPU-Z VALIDATOR
So I've given up on using them as a reference for this purpose. IDK if someone can unlock these, or if they just spoof CPUZ.
And again a superclock with normal Voltage.
They all seem to be on ASUS P6T motherboards. ??????

Look at the voltage - there is no way in hell that chip is 7.5ghz at 1.25v.

That's what I'm saying. CPUZ is useless for confirming unlocked CPUs. It seems to be ASUS P6T motherboards are involved in this stunt.
But there IS a voltage hardmod that spoofs the V.sense pin on the VRM controller and the MB can't tell what the Voltage actually is.
But these are always the fastest one there. So I think they're bogus. Having the worlds only unlocked CPU of that type, and it just happens to be the best overclocker too? Nobody's that lucky, or that good.

I remember reading somewhere that CPU-Z shows the processor's current VID instead of the actual voltage if it can't access or don't support the voltage sensor. This would at least explain the voltage displays of the CPU-Z validations.
