Hi all :),
So last year before Ryzen 3000 announced- I sold my 2700X/X470 rig and before the prices dropped :).
since then I was using my Xiaomi notebook pro and i3 7100 Desktop PC.

last month I saw this X99 Turbo unlock and I could not resist and ordered Kllisre X99 (X99Z V102) MB + E5 2620V3.
To day I got the parts and just finished assembling the PC, I must admit that modifying the Bios was nerve wracking and the reboot after flash was scary :).
I used the new method of injecting the FFS driver to the bios:
I had small issues: Bios is locked on this MB so I had to use AFUWIN 5.12 to backup the bios and later to flash the modded bios:
AFUWIN 5.12 - скачать
If any one needs help to upgrade this bios -feel free to ask (mine was 8MB .rom).
in CB R20 the all core boost is 3.1Ghz because of power throttling (85W is the limit), in R15 it's 3.2Ghz (~965pts) and power usage is under 75W.

Hi Hwgeek
I have bought the same MOBO and CPU combo and would like to know the procedure to follow using AFUWIN 5.12, I suppose it is the same process described in
just using Afuwin instead FPT but I am not an expert and would not like to brick my new MB.
Thank you all for the material you post and big help to the community.

Hey guys!

Have an x99 Asus rampage V and 5930k at 4.57ghz

Doing straight 4k and was wondering what xeon would give me the best upgrade . I saw the 2696 v3 for $276 but missed the boat.

Asus has this long list of cpus
Asus Rampage V cpu support

Problem is I am having difficult of seeing the difference and the xeons seem to clock so low.

Any guidance any of you could send me? I'm willing to pay $300

I figure I could sell my 5930k for $75-$100 so if I can upgrade and beat a 9900k why not. Will push my system for another 2-4 years.

Does anyone know how to remove the Nominal or PL 1 settings in a bios?, If I set my bios to Level 1 instead of nominal I get my cpu to run x23, 300mhz less that its base clock x26.
However if I run it Level 1 and then use cable guys efi driver before windows loads. My cpu will run at x33 on all cores and score 5050 in cine bench R20, It will not down clock.
cpu being a E5 2697 v3 on a Msi Gaming Carbon Pro with microcodes removed from bios running ucode 27 in windows. I can confirm after extensive testing. In the advance power management.

Config TDP Level controls the throttling, I have Nominal, Level 1 and Level 2, however I can only set either nominal or level 1 (down), This needs to be modified or delete or bypassed but I don't know how.

SVID off in bios + for -offset mode in MSI bios use ffs ser8989_S3TurboHack.rar

( ser8989_S3TurboHack)
However it runs x32 PL1 (down) under Avx2
Nominal under it throttles to x26

( v3x4-3x4-0.10b-i306f2-rc9 )
Nominal Gives me x37 but throttles to x30 under AVX2
PL1 (down) Gives me a Flat x33 and doesnt throttle under AVX2

Here's my bios with my modifications, I am running ucode 1F, I have tried every other ucode only 1F and 27 gives the best results. mcupdateintel.dll is deleted and microcode is removed from bios already.

Just change the .pdf to .rom and you'll be able to use it with open it.

I would take the 2697v3. Aliexpress sells them for 138$, I bought one the other day (I live in Norway)

Hi,

I have a Klissre X99Z V102 and already flashed the unlocked BIOS. I have 2 issues:

- The 3,1Ghz Turbo is not sustained on my Xeon E5-2673 v3. Cooling is sufficient (TR SB-E) and temperatures are very low. Something still is holding back this CPU. Does anybody have a suggestion?

- I use a pair of 8GB reg. ECC DDR4 2400 Sticks - not matter what memory speed I set in the BIOS it always stays at 2133Mhz.

Maybe someone who also owns this boards can help me out?

Thanks,
Chris

EDIT: It seems there is a TDP Limit in Place. Any way to extend this limit in bios?

Hi

Your Xeon can handle a maximum RAM speed of 2133 and many Chinese MOBOs can't overclock RAM even though it says so in the BIOS and especially not on Xeons.
I had a similiar problem when unlocking a 2678v3 on MSI Raiser X99a.
I followed the Miyconst guide on youtube but the turbo would'nt go above 3.1Ghz even though 2678v3 has a turbo of 3.3Ghz.
I tried several times flashing with and without the reducing the power to the CPU by Xx millivolt, same problem.
However I solved this by applying a registry fix mentioned by Tech Yes City, Bryan mentioned a registry patch from Intel in his video from 2020.
And Voilá! after applying this to the Windows 10 installation it worked flawlessly now having all core turbo of 3.3ghz.
I suggest you look both these methods on Youtube and combine them. I followed Miyconst and applied the TYC reg hack to sucess.
I contacted Miyconst about this and he had applied the his own method to the same MOBO as I but had no problems. He could'nt explain why that reg hack was needed but mentioned it could be because of Windows 10 patches (if you use Windows?).

Having that said It's the TDP of the CPU that decides the turbo can be sustained or not, not the temperatures in general.
There's no way you can edit or change the TDP value, it's hardcoded in the CPU.

Good luck!

I have the same CPU and it is the TDP that is causing it to not sustain the full 3.1GHZ. Whilst it is a 12 core, I do kind of regret buying t as I did not do enough research into turbo boost and how the hack works.

But it is two things, heat and TDP. As Turbo Boost is only meant for 1-2 cores at 3.1gz and yet with the hack we are pushing all 12 cores to 3.1ghz. This increases the power consumption which causes the heat threshold of 86 degrees celsius and TDP of 105w to be reached much faster.

One thing is easy to sort out, heat. Get a water cooler or a good Heatsink cooler.

The TDP is the hard problem and there is nothing that can be done to the CPU. The only thing you can do is undervolt the CPU in the BIOS of the motherboard.

On the Chinese boards form Aliexpress, you will most likely need to modify the BIOS and flash the modded bios.

I have reached the most stable undervolt on my CPU's at -0.05v

Anything lower and the PC will lock up, BSOD and just not run stable for a long enough time.

I have two of the CPU's in PC's running as servers 24/7 at 100% CPU usage encoding my media.

It still doesn't stay at 3.1ghz all the time, but it is what it is. It will fluctuate between 2.8 - 3.1 ghz constantly

I am currently looking into getting two 2666 v3's. They have TDP's of 135w and a max turbo boost of 3.5ghz across 10 cores. This will be on my lounge PC for playing games and my work PC.

So in summary,for the x99 2011 v3 Turbo boost hack, you need to aim for higher TDP.

My daily driver desktop is running an i7-5820k OC'd to 4ghz and it never reaches its TDP of 140w. Under full load it only ever gets to 105w @ 4ghz. Granted this is not Xeon and does not have the Turbo boost hack.

new to this tread. Brilliant comments. I'm a long time owner operator of Tylersburg X58 / i5500/5520 & moved into X79 & still running X99. Here to learn & share my past & new experiences with hopes to keep newcomers interested in the fun of Overclocking on classic tech. {:
Still in service: All ASUS: Z8NA-D6c WS, P6X58-E WS, Z9PE-D8 WS, P9X79-E WS, Z10PE-D8 WS, X99-E WS USB/3.1. Used Rampage ROG since the X38 & some after.

Glad to have you here. There may not be many people who respond because we have moved on, such as, in my case I am running an hp proliant server now..

I have the Huanan/zhi X79 Deluxe motherboard with an E5-2690v2.
I understand I cannot mod the multiplier or BCLK to overlock the CPU but I can overclock the BUS.
I have tried SetFSB but my computer but no luck there as I kept on getting crashes or no zero improvement in clock speed.
Does anyone have a SetFSB setting I could try or can recommend me another way to overclock my computer?

As I recall, back in the days when I was using SetFSB with a Q6600 (admitedly, awhile ago) there is a chip on the motherboard with a specific code/designation. Find the chip, find that code...go to SETFSB drop down menu and look for that same designation.

For price/performance, I suppose DELL T5810 might be a start as a decent XEON-based budget workstation (with some gaming too). Find a nice one for around $200 (incl PSU, motherboard, 32GB DDR4) and then upgrade the CPU with an E5-2696V3 (18C/36T; $45). Add GPU (used RTX 2080TI or better) and 1TB SSD drive for OS. Perform a turbo-unlock (with undervolt) to max out all core turbo freq.
Downside of going the T5810...it's not Windows 11 TPM 2.0 compatible (though there are workarounds) and there is no NVME boot capability. Benefits of going X99 (w/V3 or V4 CPU)...relatively solid price/performance (incl. AVX2 instruction set) over X79.
Frankly, in the current market...I decided to upgrade my daughter's X79 system (Huananzhi X79 deluxe, 4x8GB DDR3 1600, E5-4627V2 (8C/8T, 3.6Ghz) to Ryzen 7 5800X ($175) + ASUS ROG Strix B550A Gaming ($80) + 2x16GB DDR4 3600 (Trident Z Royal, $80). I expect the net cost of this upgrade, after selling off the used parts, would be around $200.
Unless you already are vested in XEON (e.g. owning an expensive X99 motherboard)...I would go the Ryzen route...else look at 10th gen intel for a budget friendly build. IMHO.

I just found this thread and it is fun for me to read about other's experiences, I've been building a with a lot of 2011-3/4 based system for years.

One thing I have discovered is the variance between Dell T 5810 boxes. One supported the E5-2696 V3 just fine, which made for a very.nice cheap system. T5810's can be had cheaper and cheaper, there was just a collection of 5 on eBay for $75 each and a total shipping cost of $30 for the lot. All with 32GB of RAM. And of course you can get an E5-2697 v3 for under $20. The combo is still a nice value in some cases.

But The BIOS and motherboard rev differences seem to drive which T5810 will take the E5-2696 v3 ( a good upgrade for the 2697 but more expensive in the $55 range). The single thread speed improvement IS noticeable.

So on the T5810, updating the BIOS may REMOVE support on the T5810 for a CPU. All those little strange-but-true details that run somewhat counter you what you might expect.

Also note used T5810 boxes may or may not have the aux power 6 or 8 pin cables for better GPUs but they CAN be ordered as a part and just plug into a socket to install. And of course note the differences in power supplies across different T5810.
