Memory overclock *The 70$ PNY 2666 kit

This thread is designed to help with overclocking on budget memory modules.  (At your own Risk!!!)

You know, the memory kits that Thaiphoon burner doesn't seem to read? (I'll show you here how to get the information. Be it complete or not....)

But just to let you know, this will be a fresh start OC ABOVE XMP rated frequency. 

 

The Kit. MD16GK2D4266616XR

 

Speed Compatibility - 2666MHz, 2400MHz, 2133MHz - 1.2v

 

The Look - Not horrible, but actually reminds me of that Oloy memory if any of you are familiar with it....

Which this kit would be about the same quality if given a similar speed and timing set.

Does NOT need these heat spreaders. Totally just for looks.

The Thaiphoon Burner  - Well as you will see here (first spoiler) Eeprom tells us nothing.

But if you hit that report button.(second spoiler below)...Which will also tell you the PCB revision of your memory kit as well.

As you'll notice, the memory kit is running XMP. I have used it for general purpose and F@H. So far so good. Stable. No heavy load testing yet.

(testing using OCCT memory linpack screen shots in the OC posts below)

Played some Need for speed at most for the gamers out there. But nothing heavier than that.

Adia64 cache and memory benchmark *Located in the tools tab at the top of AIDA64* (Our initial measurements)

 

XMP rated 2667 16-18-18-35 2T 1.2v 

56ms latency but only 35k mb/s read writes.

Decent latency and poor bandwidth.

Check HWInfo64 for Dram temps.

=None.

Voltage steady good 1.2v

VCCIO 1.152v (bios set 1.1150v)

System Agent 1.148v (Bios set 1.1150v)

VCCIO and SA increased for overclock. Also used for daily on B-die, I did not change the values.

Are higher than input via bios, but that's how Asus boards roll. OV the shit out of everything. 

With XMP, on this board, they will default over 1.4v - So users, keep these manually checked!

Reserved for OC

 

First OC - Simple

XMP enabled. Adjusted manually Dram Frequency to 2700mt/s

Set the Dimm voltage to 1.25v manually in bios. F10 save. 

 

Cpu 8700K stock default cpu settings. (Testing memory only)

Quick OCCT linpack memory 20 minutes.

Looks pretty stable. Daily tasks, browsing, watching video and gaming is fine.

 

Memory latency lowered just a little, but the frequency change wasn't enough to boost the bandwidth in any significant way. On the right track so far with minimal changes. (timings on auto)

 

Spoiler

594666603_PNYOCI2700mhz.thumb.png.8123e500553d5e176f40c49907b8e0d8.png

 

The next available frequency in bios is 2800mt/s.

Will try this one Dram frequency change only, 1.25v 

Figured I'd drop a validation this time. what the heck right?

Testing again simple OC, timings auto.

Notice tRFC is getting looser. Results from timings on auto.

 

2900mt/s (1450mhz effective)16-18-18-35 1.25v - 

Another Validation - 

https://valid.x86.fr/vz5f3c

53ns latency, bandwidth creeping up with frequency.

Reserved for OC II (manually changing timings)

Reason-

16-18-18-35 is only good for 2933mhz 1.25v 

This timing set created errors at 3066mhz. 1.35v

 

.......

So changed the timings instead. Testing crudely. 

18-20-20-40 1.35v (all other timings on auto xmp still enabled.)

3200mhz. And looks pretty good. Not the greatest results, but making some bandwidth.

Dude where's this post?

 

Here it is!!

 

3333mt/s (1666mhz) 18-20-20-40 1.35v

Passing 20 mins OCCT and feeling good about the latency here. Getting close to under 50ms, which is pretty decent for most of the timings set at auto.

3400mt/s - With looser yet timings

20-22-22-42 1.35v - all else auto. 

20 minute quicky OCCT passing.

Would not do CL-19-20-20-40. So, F-it looser then.

 

This screen shot it 3400mt/s, I am going to stability test 3466.

Highly doubt we'll be seeing 3600mt/s on 20-22-22-42, but gotta pass 3500 first.... Should get interesting.

I'll go as high as possible, primary timings only at 1.35v. From any experience with Hynix, they usually don't scale much from additional voltage, I may go as high as 1.4v, but it probably won't help.

 

The SS -

P.S. look at that 4th core. Hotter than a MF. That's stock clocks! lol.

It hopefully will get better. Push them up as far as possible and then go on a tweaking spree. See if I can't squeeze in a little extra performance. 

 

So far, simple quick dirty and at least trying to test for errors. When I get something dialed in, I'll aim for 2 hours minimum screenies.

 

And thank you 🙂

I usually let it go for a couple of hours if I am going to show others what i am doing.. but behind the scenes it has already run for hours under stress.

 

You are most welcome, You are awesome man, keep on keepin on 🤘

Will do.

 

3466mt/s 20-22-22-42 1.35v 

With AiDA64 little by little, getting increased bandwidth with sacrificing a little latency. But not too horrible. If this was on my 2700x, the latency would be closer to 65ms (I'm guessing)

 

This while 3500 posted and will now test, post back in a bit. Same settings.

20 minutes again. Rest on auto, cpu stock.

3600mt/s 20-22-22-42 1.35v

Tested OCCT about 50 minutes (free version is only 60 minute restricted)

 

So here it is. I'll be pushing further though. No reason to stop yet. Not quite 1000mt/s OC yet.

But am shocked at the results so far.

Last one for tonight maybe.

 

3700mt/s - 20-22-22-42 1.35v

All other settings auto. 

 

It likes that 20 cas!

3733 fails under a minute. 

Example - 

And will loosen Cas to 22 and leave the rest.

Next after this 22-22-22-42 and see if it will get up. 1.35v.

Had to go looser. 

The rest still on auto.

Now at  3733mt/s 22-24-24-44 1.35v

3866 is a NO GO.

 

Tried fail post count 5 and 6 tries. Standard is 3. This gives the PC extra chances, you never know it might post up on one of those attempts! So it's an old trick I use for adventures like these.

Tried memory retry button several times.

Tried 24-26-26-46

Tried 1.4v / 1.45v

NOTHING- all above just fail safe to defaults.

 

3800mt/s is good to go. Posts right up.

22-24-24-44 1.35v is just dandy. 

 

Will tweak from here. Maybe improve the performance a touch, maybe not. So far more voltage does nothing. 

Maybe even some 3D comparisons.

 

...Although Im not sure would be good for comparison. 3800 untweaked vs tweaked or just xmp vs 3800 tweaked??

No stability testing yet.

22-24-24-44 1.35v

TRFC 665 to 605

Dram Write latency 19 to 16

(did not change average scores, could have left these on auto)

880993909_3800mhztestI.png.6a10c7b331eb86f990f1b2bb1a54ff8a.png

 

Same as above with HT disabled.

 

Spoiler

468424715_3800mhztestIINoHT.png.756e0bb7c718830fe762a54eda1346d9.png

 

This is a very considerable improvement over the 2667mt/s profile despite the Cas-22. 

Not horrible for a pretty cheap under-dog kit imo.

 

Oh, the HT enabled/disabled is to demonstrate the L3 cache outcome, in case any where wondering.
