No idea as I didn't research the cooler before I bought it. I had thought aftermarket coolers would have been enough. The Se-225 XT comes with 2 fans for a push-pull config. But as mentioned above, the pull fan emitted a high-pitch noise at high speed so not good. Unless I got a defective cooler.

Mine is 13700k.

I did. -0.1mV vcore offset in bios. So far no issues. Didn't try lower because didn't want to corrupt my windows testing lower voltages.

I think my mobo voltage is causing some of the thermal problems.

[attachmentid=11398289]

The voltages for the core ratios looks really wrong. Need to research more on V/F voltages.

Bios allows max -500mv offset which is much better than the -100mv limit for vcore offset. I  think this is the key. I didn't have time this morning so I tried the usual -100mv offset for 43x to 54x. Max voltage in windows was 1.406v, same as vcore offset -100mv. The difference is that lower ratios are stock voltage.

In the meantime, anybody can give opinion or tips for correct voltages on this?

Edit : On skatterbench YouTube video, their reference range is as below:

[attachmentid=11398291]

Vf point 1 to 4 is similar to mine. The rest of my vf voltages are just too ridiculous. Looks like my challenge is not so much undervolting the 13700k, it is actually correcting the VF curve first then undervolting. My VF curve is not a curve at all. More like a steep cliff! Lol.

AFAIK some (or most) Z mobo will behave differently when drop in a K sku CPU and will default to different setup, ie PL1 & PL2 becomes unlimited. Problem is ur Asrock mobo VRM is underspec and is dumping loads of voltages & heat out just to run that CPU unlimited. Compounding with a insufficient cooler, ur system is more efficient as a spaceheater than running at its full potential. I'm afraid to say but I reckon its better to change that mobo to something better, MSI Z690 Pro-A is probably the cheapest decent one but mostly are DDR4.

Another you could consider if you can stump more money (and selling that Asrock mobo) is this Asus Strix Z690 https://shopee.com.my/-ASUS-ROG-STRIX-Z690-...4e-1a87517e6390
it is a MATX tho

Giga Aorus Z690 looks quite good as well

If ur a bit more adventurous you could also put in Thermalright's anti bend frame.

Z chipset seems to be agnostic of other mobo components ie VRMs capacity. It probably doesn't care if its shitty 9 phases or Asus level 20 phases, as long as it detects K sku it will ramp up the same.

Another possibility could be this;
News from Reddit seems to indicate that Intel is locking ADL & RPL undervolting capability with newer bios updates

Now many have individual shopping sites, ie AllIT, TMT, viewnet, etc, but many of them seems like rarely got updated some of their prices have not changed in years

Price difference is around RM 200.
13500 slightly more L2 and L3 cache, more E core and slightly higher clocks. Worth the extra RM 200?

Ask urself then, is the Ecores going to be useful to you? If purely gaming then No. So go for 13400

But if you do have productivity use for the PC, then it would help so go for 13500

If you can add RM 200 more then get 13600kf

If you can add RM 200 more then get 13700/F

So where is ur limit to add more then?

If you afford the addon to addon, then I would say a 13700F or any 8 pcore CPU as games now requires 8cores as the playable recommended specs

My use case is for gaming only. I wouldn't mind getting 8 core cpu but both AMD and intel pricing for local market too high for me. Even if I keep for 3+ years.
I think 1.1k would be the most I would want to spend on CPU

Both maxed PL2 to 154W, so even the much maligned cheapass Asrock B660 Pro RS can run them set at its max power limit of 160W however that needs a decent tower cooler ie 224XTS (new version).

The main reason i want to upgrade is im running out of storage space and i refuse to add more HDD / 2.5 sata because i cannot tahan trying to cable manage dy 

So buy new mobo with 3 nvme slots. Thus looking at new CPU as well 

Guys, if I can get an unopened but old stock scythe Fuma 2 rev A (did not have LGA1700 mount only up to LGA1200) for RM 200, is it worth it? I would still have to spend a bit more for the 1700 mounting kit tho...

Im looking at its perfect compatibility when 4 RAMs are installed without having to shift the front fan up.

Since MSI Pro B660M-A can handle up to 12900K (without OCing), it can supposedly handle 13700KF as long as you dont plan to OC, but can run up to max PL2 TDP. And if Pro-A mobo can do it, then B660M Mortar & Tomahawk oso can support it.

With good airflow over the VRMS it can handle even up to 12900K

Disable via bios but why bother to disable Ecores?

When will the price drop?

Congrats but I would put off upgrading to Meteor lake and wait for the generation after that. Due to node size limitation, MTL will only top out at 6 Pcores in which the next iteration predicted to get a node shrink and will return back to full 8 Pcores. This is similar story to Rocket lake i9.

What you used to assign the P&Ecores? I had to manually set core affinity when I run Handbrake so that it uses Pcores instead of defaulting to Ecores.
