Could 1230 v3 be "turned into" a 4790K?

[Sabotaged_Enigma]

I'm playing with my Z97 board and E3-1230 v3, and I just flashed microcode 07 into the BIOS, now the CPU can run at 3.7 GHz on all 4 cores.
Then I came to wonder, since E3-1230 v3 and i7-4790K are basically the same thing, is there a way to mod the BIOS that makes it "turn 1230 v3 into 4790K" thus unlocking multiplier?
Though I already have a negative answer because the CPUID is written in the chip itself, I still want to hear your opinions. Thanks.

Devil's Canyon has better binning and some physical changes to support the higher clocks though, it's not the same as Haswell Refresh (4771/1231v3). 1230v3 would at most be comparable to a 4770K even if you could theoretically unlock the multiplier - there were a lot of 4770Ks that struggled even to reach 4790K stock turbo bins.

I'm surprised you managed to get past the 3.5GHz all core cap with just microcode. The hard locked turbo table on E3 was been annoying since v1.

The 4790k is haswell refresh with unlocked TDP/Multi, better integrated vrm, and have IGP...

It is possible that all core turbo hack is working with not just the 2011v3 xeons but the desktop versions when older microcode is used.

Yes, that non-K all-core turbo has been achieved. I'm talking about the locked multiplier...

The multiplier cannot be unlocked. However, it should perform like an i7-4771 CPU regardless. Is that not enough? There's no use beating a dead horse, it's a 10 year old low-end server platform that's basically borrowed from the mainstream desktop counterpart, if you need more performance, you must upgrade.

Didn't Intel also change the way the multiplier was locked from Haswell onwards? Hence no more of the "partially unlocked" Sandy/Ivy +400MHz OC starting from LGA1150.

On Ivy Bridge I suppose if you could get into the MSR register that determines locked/partial/unlocked, it might be possible......but clearly Haswell changed.

xeon e3-1230v2 3.7ghz?

im aware that the turbospeed is 3.7 ghz but do anyone know how i can make the cpu to remain at permanent 3.7 ghz speed? my mobo MSI ZH77A-G41

Unlocking multi... I dont think that is possible yet.
But if someone hack the microcode in the cpu it can work.
I think only the old Atom cpu-s can hacked this way today.

Indeed.

All E3 CPUs have their multiplier fully locked cannot be unlocked
All E5-1600 v3 has unlocked multiplier, while all v4 are fully locked and cannot be unlocked
E5-2600 and 4600 v3 and v4 both are fully locked and cannot be unlocked

There is a turbo boost exploit that allows the E5-2600 and -4600 v3 that will cause the CPU to apply the 1-core boost multiplier to all cores, which involves removing the microcode from the BIOS and letting it boot pure, then either loading the microcode yourself or letting the OS do it on the fly (Windows loads mcupdate_GenuineIntel.dll as part of the boot process, removing this file will cause the OS to boot with no microcode update loaded), but this affects ONLY retail stepping Haswell-EP and EP 4S CPUs. The ES chips are unaffected as are the E3 series.

I've done it with my 4669 v3 and X99 Ultra Gaming, I use a custom driver provided by VMware to load whatever microcode I want, or I can just let Windows override it, it's interesting that it can boot without an ucode installed. My ucode collection is a bit outdated now, Windows 11 comes with 0x44, the last dat I have for it is for 3D, circa 2018.

I have to warn that running an older microcode also reintroduces multiple errata and in fact even reenables TSX (which was disabled by Intel due to hardware lock elision causing memory corruption), run an older microcode or the CPU pure at your own peril...

Microcode manipulation on Haswell variants is rather easy, but the multiplier lock is either fused or on the CPU firmware, it cannot be unlocked.

My experience with a 1230 V2, the Ivy Bridge predecessor, was that the processor itself was amazing in terms of bin, it only required something like 0.6V to operate full speed, but the base speed was just 3.3Ghz. I was able to overclock it +200 MHz because my Z77XUD3H motherboard was able to select +2 on multiplier. It could not be overclocked further and there did not appear to be a way to do so.

It's good enough. It's not my main gig anyway.

There is not much difference between 3.7 GHz and 4.5 GHz in that era. You'd really have to be around 5.0 to really notice, in my opinion. Would suggest a i7 5775C (~$85, eBay) if you really like the Z97 motherboard/platform and want to max it out.

Thanks for the info!

I used UEFI BIOS Updater and flashed microcode 07 into the BIOS, then it worked very well!

Also the 1230 V2 that I had had an amazing memory controller, I had some good ram overclocks with that and the Samsung DDR3L YK0 "greens".

Yes I observed the same thing here. It needs very low voltage. I think what a pity and what a waste of good binning if multiplier is locked...

I believe I have the same RAM as yours, but only mine is made by Ramaxel and has blue PCB. It can do 2933 MHz 13-15-14-36 @ 1.6 V. Amazing, right?

Sounds pretty stellar for DDR3. The YK0 ram can easily be distinguished by the text printed on the ICs. If I recall correctly the CH9 was also good for overclocking.

1230v2 and 1230v3 had the exact same turbo table I think. 37-37-36-35. So 35 wasn't an overclock, just enforcing the existing all core turbo spec. Same experience on my Z77 Extreme3.

More frustrating for v2 because 3770 could theoretically do 43-43-42-41 on a Z77 board.

Samsung 4Gb YK0 DDR3L 1600 ECC unbuffered low power from a Fujitsu server. I think that is the same green ram just for servers.
no heatsink but is is very cool

It is, that's quality ram. You don't need a heatsink for that part.
