Alder Lake CPUs common discussion

[GerKNG]

Thank you so much for your response! so with your kit, running at 3200 allowed you to run at tighter CAS latency timings?

it behaves pretty much like ryzen and 11th/10th gen.
what was stable before is now stable as well. all it needs is manual VCCSA.
3200 CL14 worked just like with my 5800X but the 3600 gear 1 with XMP gives me better (2-3%) gaming performance. (i have trident z neo 16gb dimms (32GB) 16-19-19-39)

This may be relevant. I don't know these are adjustable, possibly hidden BIOS settings :

• Power Limit 3 (PL3): A threshold that if exceeded, the PL3 rapid power limiting algorithms will attempt to limit the duty cycle of spikes above PL3 by reactively limiting frequency. This is an optional setting
• Power Limit 4 (PL4): A limit that will not be exceeded, the PL4 power limiting algorithms will preemptively limit frequency to prevent spikes above PL4.
• Turbo Time Parameter (Tau): An averaging constant used for PL1 exponential weighted moving average (EWMA) power calculation.

none of these three settings are available in my gigabyte bios.

Excellent, I’ll try that, my kit has the same timings as yours! Thank you again for your help, you mind if I ask for advice once I put my system together?

I think i'm gonna go for the 12700k/z690/2x8gb ddr4 3600c18. Cant wait to play with it. just need a block for the lga 1700 socket

 

[phanbuey]

Just got 1400 quid to blow, so i'm gonna get a 12600k with a z690 D4 board. so looking forward to it. Only thing is, i'll have to get a lga1700 compatible water block too for my loop.

You don't need it most likely... the holes on most water blocks fit 1200 and then cut out to also fit x299 they overlap the 1700 holes... my block went right in no issues whatsoever.

They make it sound like the holes are so different, they're only off by about 1.5mm - super close and in between x299 and 1200. 99% of water blocks that have the cutouts for intel sockets will work as is.

My CPU is a ryzen 2600x, so socket AM4, i doubt my block will fit on a LGA1700.

It didn't come with an LGA Bracket? -- In any case most LGA 1200 blocks will work; in case that info saves you $$.

Seems like people over at overclock.net are having a lot of success overclocking both DDR4 and DDR5 on Z690.

This one on DDR4 reportedly couldn't get 3866 to work before, but on ADL has it running DDR4-4100 C14 . And this is with a relatively cheap Strix D4 :

This guy OC'd some DDR5-4800 to 6200 C32. The total latency here 51.5ns total is right in line with the DDR4-4100 C14 above. This is on an ultra-expensive Apex though ($840).

DDR5-6600 CL32 Trident-Z spotted :

Thinking that within a year, DDR5 is going to dust DDR4. Not yet, but not that far off.

Midrange boards, like Asus Prime-A, already support 6000MT/s (via Asus webpage).

So this will fit LGA1700?

 

[phanbuey]

yes that one will fit .

i really hope this gets sorted out quickly.

Does HWiNFO show the reasons for throttling for the new 12th Gen CPUs? It should.

There might be a clue in there what is causing the throttling that you are seeing. It might be caused by the voltage regulators or a current limit that is set too low. When stress testing, the Limit Reasons data should all show No.

Here is an example of this data on a 10th Gen CPU.

I also have the XSPC Raystorm waterblock . The Intel and AMD versions were sold as two separate blocks but you could buy adapter kits to convert from one to the other. The aluminum bracket will fit on top of the AMD version block but you still need the bottom bracket and the correct posts, springs, nuts etc. I believe Intel/AMD have different threading pattern to the female bottom bracket holes. The new stock metal 1700 OEM socket plate also has 4 bumps (rectangular) from the socket attachment screws The original XSPC Intel 115x bottom bracket has holes or a cut out for just 3 bumps (1156/1155 has triangular socket attachment screws). It looks like the original XSPC 115X bottom bracket won't lay flat against the back of the motherboard?? One side fits but the other won't and will be higher due to the two corresponding rectangular bumps on the opposite side of the 1700 OEM socket plate.

bottom brackets will not fit - only top mount - you can use bolts with no backplate and not over-tighten block or use another bracket / make your own using slot brackets.

Am i just better off buying a new block? was looking at this-
https://www.corsair.com/uk/en/Categ...PU-Water-Block/p/CX-9010013-WW#tab-tech-specs

I already have the loop setup, so may as well water cool the i7 12700k as it seems they "may" run a tad hot.

but what is the new high or safe voltage compared to 14nm?
not that we end like with Zen 2 where people pumped 1.4V+ with high LLC into their 3700
normally i'd go (max) 50-100mv above stock.

The general vibe I'm getting(keep in mind I have no hands-on with AL yet) is that voltage should be kept below 1.4v The observed voltages from Intel automatic regulation seem to max out at around 1.35 to 1.375, so it should be safe to bump it bit higher. But remember, all the testing done so far seems to also indicate that Intel is really pushing the limits of AL dies to get the most from them, thus not a lot of headroom exists for OCing. There's not enough raw data about Intel's new 7nm(ish) process to know where the absolute limits are.

Given how expensive and high demand they are, my current advice to anyone doing OCing with Alder Lake is to go easy on the voltage and be happy(for now) with whatever OC you can get from default or near default voltages. The benefit is not worth the risk at this time. Once more testing has been done by reviewers and "elite" overclockers the limits will be better fleshed out.

looks almost like alder lake "K" CPUs get treated like non K SKUs.

What else would you expect? Infinite CPU clock?

that i get an unlocked CPU when i buy an unlocked CPU?

It is unlocked, but it will only run X MHz by default

 

[GerKNG]

It is unlocked, but it will only run X MHz by default

we don't talk about a stock CPU.

this is a manual overclock to 5Ghz all core. and Alder lake currently forces the CPU down to 100Mhz below the single core boost or -200 Mhz when you're more than 200 Mhz above the Single Core boost. (like it is on my screenshot)

4.9 is the SC boost.
going to 4.9 all core = 4.8
5 Ghz all core = 4.8
5.1 Ghz all core = 4.9
5.2 Ghz all core= 5.0
...

Reports of AL having issues with some denuvo games, is this true?

I am guessing if true simply disabling the e-cores will fix it.

 

[phanbuey]

Interesting --I did not see this behavior on the 12600k on the Aorus 690I we built.

Was ratio 51, auto voltage, efficient turbo -> on,

We did notice TVB ratio clipping doesn't work even though it's an option, likely due to the 12600K not having TVB.

Or just set default affinity to a P core.
