Overclocking Gskill DDR5 C30 6000 2x32 (64gb) to 6600, timings tight. W/ 14900 ks UPDATED

[ir_cow]

Gear 4 has never worked for me on 12,13 or 14th. But the same thing happens. Latency goes up and now you need 12,000 MT/s to match 8000 performance.

 

[RootinTootinPootin]

195 points and all. That’s good right? lol.

95 or 195? 95 is about darn good

But I tried 8000 on this thing and it was on gear 2 and I kept downclocking it until I hit like 7200 and then I was just like fuck this,

you have DIMM Flex on? also probably due to you are running Dual Rank sticks (2x32GB) but that board is capable of doing 7000 the least as far as I have seen even for dual rank sticks.

you don't need to push too high voltages if you have a good IMC also a good binned chip (on the same AI feature page on top will display your P-SP and E-SP rates)

That is what I was worried about. Thank you Cow.

Maybe 7000 on much loser timings but I’m running CAS 30 with really tight timings right now. I’m pretty happy with it I think.
Flex is off though.

Oh, I misread that. 99 SP points, 207 points on the cooler.

guys from the other forums run CL32-34..in your case with that good of an IMC you should do better voltages

I’ve been playing with these voltages for like a week. It doesn’t do less. Lol
Maybe it does, I’m no Pro lol.
Maybe it has something to do with the 14900 KS?

can you show me a screenshot of the AI page in BIOS? what matters is the P-Core SP rating. from there I can help thru DM

Oh, it’s 115 apparently lol.

But is that CL32 on 32gb sticks?
I’m going to start trying to work down voltages individually and see what happens. Can’t hurt to try.
I think maybe I had these voltages where they were because I wasn’t stable due to the temperatures before I modified my memory and added some direct airflow. It may be stable now with lower voltages since the temperatures are so much lower?

on the lower part of this screen you can find the IMC SP rating, if you haven't seen it yet you can run the "Get MC SP" option, it will reboot to test out the IMC, on next reboot you will see a number there I need to see that as well..

I.5v on the VID isn't looking good, you chip will get toasty, and would probably degrade fast if you don't manually tune it.

MC SP is 78
VID, is that cache SVID or global core SVID?
Trying to find it lol.
But my core voltages are set to auto and not 1.5. Bios says 1.314 currently and maybe 1.45 in cinebench under load.
Not sure why that says 1.5.
My SVID behavior is set to typical.
LLC at lv 4 which is not high either.

Maybe those are some sort of hard caps based on the bios Asus Multicore enhancement calibration? Set to enabled remove all limits.

I was just gonna say Im over 8000 on a 1DPC board with a 69 IMC SP.

1 DPC changes it all, hes using a 2DPC, on a 2DPC yields on SP rating has an impact, also on lower tier boards, the MC SP Rating does matter, I also am not much of a fan (everything on the Internet for me needs to be taken with a sack of salt, since I am not a normie and I can test on my own)

also FAIK, you're pretty much feeding the TX and VDD2 ludicrous voltage on a lower IMC SP Rating, I'm just doing it timidly on my daily 8600MT's (like 1.37v on vdd2 and TX is just 1.32, I have more headroom together with a good IMC, in fact I can boot 8800MT's gear 2 with mine, I am just waiting for the RAm Blocks)

Not sure if trying to teach me something, or didn't realize I mentioned is specifically due to OP not using it.

 

[D007]

Well, I tried for a while and even getting it to post at 7000 required 1.52V lol.. Not stable.. Thats at 38-40-40-40-96

The z790 Dark Hero has a "lower" rating? this is supposed to be a top tier mobo lol... T
X 1.35 and VDD 1.45 on 1.4v 32gb ram is ludicrous?
I mean the ram is rated for 1.4V and you're saying 1.45 is ludicrous?

Jah, your board is a Hero man, upgrade of regular Hero, 2nd to none, there's like 2 boards better than yours...... 2 slot Apex makes it easier, but isn't a necessary purchase.
Need Single Sided 32GB so 2x16GB A-Dies, and you would replicate @sneekypeet settings (for example) and be done.

Nice thing is you have time and money. Send back the memories if they don't work and find suggested set/s of memory to get 8000mt/s and higher. Should be no problem.

 

[ir_cow]

7000 Dual-rank for 13/14th isnt going to be stable, let alone post for you. Sorry to say

 

[ShrimpBrime]

IMC SP Rating,

What say, his was 69? That's below average. 70-80 is average IMC. He's loosing the lottery.

I always thought 32gb wouldnt cut it in todays gaming and I'd end up losing performance.
2x24 (48gb) seems difficult to hit 8000 as well.
ugh..lol

ya ya, I know. We did establish this in one of 4 threads haha!

2x16gb. 32 total. Performance here. IMC seems weak.

Everyone else is gaming 32GB memory installed pretty much as a standard these days. The system will notify the user when physical addressed memory is running low on space and will recommend turning off some applications you don't need like the Aura lighting for your keyboard and all the stupid Asus garbage for example. But you should be fine I think. GPU is badass, so I don't see any issues.

P Core SP is 115
MC SP is 78

78 is good. Ask @ir_cow what memory kits he would suggest. He's tested quite a few!

 

[ir_cow]

Mines at 78 as well. I had a 14900K with 82 that could barely post 8000. Another in the mid 70s that maxed at 8200.

Between Igor data and my 4 CPUs I've tested. Doesn't matter for air and water cooling. Just my opinion

That’s so confusing lol

 

[Dr. Dro]

That’s so confusing lol

That's because the scale between SKUs is different. The Igor's Lab data applies only to the i9-13900KS, the i9-13900K and i9-14900K/KS have different scales.

 

[ir_cow]

Higher number = less volts leakage. Less need for same. Once again I think it's only for squeezing out that last 100mhz for a world record. Which btw they use 1 DIMM and disable half, drop the CPU the lowest it can go. So it's kinda a odd achievement. None useable.

I thought that was only the CPU rating because of the vcurve is different . Now I'm questioning myself lol.

It's the predefined v/f curve that affects the prediction algorithm, yes.

The last and fastest of their kind – Intel 13th Gen Raptor Lake Binning | Part 3: i9-13900KS | igor´sLAB

Today is finally the day – loyal readers won’t be surprised by this –, for Intel’s last and fastest LGA1700 CPU we also have binning data for you once more. Thanks to MIFCOM, we were able to run…

www.igorslab.de

Due to the different V/F curve, the scale of the Silicon Prediction (SP) values also inevitably shifts. The bottom line is that a 13900K with SP 100 is not as good as in 13900KS with SP 100. With regard to the V/F curves or VID points, it should also be mentioned that, strictly speaking, each core has its own individual curve and thus requires different amounts of voltage for a certain clock pulse. The KS SKU also has an advantage here in that – at least in all the chips we tested – the 6.0 GHz VIDs of all cores were always identical. Conversely, this should mean less “up and down” for the voltage regulation on the motherboard during partial load, resulting in better stability during load transitions.

Same article regards MC SPs as completely worthless as a measurement scale, although Xaver was binning them on a Z790 Hero

The result is surprising and sobering at the same time, because there seems to be no connection at all between the MC SP and stable RAM clock. For example, the CPU with the lowest MC SP of 53 manages the highest DDR5 clock of 1950 MHz, but only a mediocre DDR4 clock. Conversely, the CPU with the highest MC SP of 89 also only manages mediocre values of 1881 or 2000 MHz.

Although this testing 199 cpus at the time was good, but was done with memory they had to work with of the time. Using DDR4 19-20-20 4000Mhz? And DDR5 was a "green" set CL 50 5600Mhz A-Die using 1.4 V MC Voltage (VDD2)....

All article Jan. of 2023 and all testing previous to that date, it's almost Jan 2025 now.

Not sure if this article is valid now with the probably dozen Bios updates (On Z690 no less) since this release also to mention way better memory has been released since this also.

But. I don't see big differences in SP ratings when following the Raptor Lake Mega thread at OCN where people share their experiences with about 1100 pages worth of end user data to browse through.
