  • I also have a question regarding the QPI/North speed. I'm using 3200Mhz as reference (and always used). Is ther eany benefict regarding SEEN performance upping this value? lets say 3400 or 3600? Keeping in mind that will probably be necessary to up the QTI/VTT voltage substantially for a minor gain??
  • Another thing that always intrigued me was if has any difference in using for ex. BCLK 200 + 20X Multi (4000Mhz) or 16B BCLK + 24X Multi (~4000Mhz) ??? Is there a benefit in using a high base clock? Or a lower is the same and have lower CPU loads at idle for instance??
Thanks :)

Nice system. With my old D14 I was able to run my X5690 @ 4300 everything stable. I could bench higher of course, but was tough getting airflow back then.. its fans were quiet and barely moved any air. Running a high bclk is preferable mainly for memory performance, and it gets the QPI up. Not only for increased reads/writes but also latency. A higher uncore is also preferable, there are differing views on max qpi vtt, but I ran 1.39v for years with my uncore @ 3600. Mostly ran 200x21 ram at 800MHz 6-6-6-20 1T 1.65v. I've got a Rampage III Formula with X5690 and a bunch of different memory. Some Hypers, BBSE, PSC, and a lil Hynix. Those ones are no fun. IIRC I had to run my IOH at about 1.25v or so once I got over 4GHz. Didn't matter if I was running a low, medium, or high bclk. YMMV of course. Make sure you check the bios now and then to make sure the voltages you set are actually what they are, some boards sag more than others in the voltage dept. Leaning towards QPI VTT and VCORE.

Hi freeagentt thanks for you helpful insight!
- Regarding the Noctua D15 it's night and day from what I was used to! Now the temps are my least concern.

- I understand the higher BCLK get higher QPI and RAM speeds. That will leave me in doubt about this 2 options:
BCLK = 160 X25 Multi = 4.0 Ghz --> QPI = ~3200 --> RAM = ~1600
BLCK = 200 X21 Multi = 4.0 Ghz --> QPI = 3200 --> RAM = 1600
- Now i can use the same speeds for different BCLK's, the only gain i see is with 160 when IDLE in windows i get 1920 Mhz (160X12) because of speedstep. And with BCLK 200 I got 2400 Mhz IDLE... Well in low task I gain the lower volts/temps with the 160 BCLK. All this because I can change the settings in the BIOS for the QPI and RAM values, even with different BCLK's and Multi's.
- I don't know if this makes any sense or as some advantage/disadvantage...

- I have a feeling what you said about checking in BIOS to make sure voltages is a thing , yes. I'll be checking more often. Because sometimes the system is all good and other times restarts. it's gets some BSOD in low/medium load operations (youtube or playing). I'll try to bump the IOH also as you suggested to check it.👍

RicK

I cant help you with that buddy, sorry. I turned off all power save stuff, no speedstep..1 clock 1 voltage. I could never get it to work right. Not like on a more modern setup. For instance, yes I could get it drop down to 1600mhz , but voltage would still be high, so in my eyes no point and a waste of time.

I set my offset to a positive number. I had my X5660 running at 4.2Ghz with a BCLK of 200. I adjusted the RAM divider so it was at 1600Mhz. With speedstep it would drop to 2.4Ghz and maybe 1.0V and under load it would jump to 1.35V.

Lol I think I was doing it wrong :D

I don't remember what I was doing. But I will remember our little chat when I do pull my x58 out of its box again god knows when and I will figure it out.

I got it working on my Z77 no problem lol.

Hi all, thanks for insight.
- Right now i've got pretty stable:
4.0 Ghz - 1.296v MAX - Vcore ( Multi X20)
BLCK = 200
Norh bridge = 3200 Mhz
QPI/RAM (VTT) = 1.25v
PLL = 1.84
IOH = 1.12
RAM (12Gb+6Gb Ripjaws)- 1600 Mhz @1.64v
LLC = Enabled

Disabled CSTATES (except Speedstep and C1E - these are ON)

  • I think it's pretty stable, run various benchmarks, as IBT very high and custom (~8000 mem ) , OCCT, played some games etc. etc. SOLID.
  • -Temps are in 60's region max, for testing. In general gaming around 50ºC to 60ºC.

  • Now some day I might wanto to try 4.2 GHz. I did little testing and did game fine @1.336 VCore , but did 1 test in IBT (high) which fail and did not try again. Maybe someone can give some ideias for that kind of overclock? Raise Vcore? VTT? PLL?

Thanks,
Best Regards,
RicK

Hi all!
Well, after a few more tests I end up with the following settings:
4.0 Ghz - 1.296v - Vcore ( Multi X20) using offset voltage (+ 0.2000v)
BLCK = 200
North bridge = 3200 Mhz
QPI/RAM (VTT) = 1.225v
PLL = 1.80 (stock)
IOH = 1.10 (stock)
RAM (12Gb+6Gb Ripjaws)- 1600 Mhz @1.60v (for now - will try lower voltages)
LLC = Enabled
C-STATES all enabled + SPEEDSTEP

- Stable as it is 100%. Temps in 60ºC in CPU.
- 4.0 I think it is done. Now I might try to bump to 4.2 and see what it got for me :)

Regards,
RicK

Nice nice! I've just placed an order for my X5670 to start my 3rd X58 build around the Asus p6x58d-e that I picked up. Twist this time, will try to run 8GB ECC Reg RAM sticks to max board out at 48GB total, beyond the "24GB max" limit

rickmig If you go for 4.2ghz, mate, try odd multiplier, those tend to need less voltage to be stable. Taco witnessed it first hand on her x5670.
(Although 920 did not seem to be affected)

There is no known explanation to this phenomenon.

Edit: corrected bold word le@ to less.

Hi!
ChineseStunna i've order an X5675 also! Just to take some comparison. But for now i'm liking very much my W3680!
UltraTaco Well the step for 4.2, form me, is to push the multiplier to X21 (instead of X20 which is now) and bump the core voltage a bit maybe to 1.336v and QPI to 1.25v. And see how it goes from there.

- Another thing I'm curious about, is SDD / NVME performances in our beloved X58. I did some tests in the HDD's and SSD I have, and would to like to have some comparison just because if I buy a new hard drive I want to know if tis OK to go with SSD (Samsung Evo 860 for ex.) or NVME is worth it... I know there are some difficulties booting from NVME with X58 right?

Regards,
RicK

rickmig very cool! I decided to stick with my trusty X5670 but X5675 definitely gives you an additional 1x on multiplier and I think W3680 is even stronger. Your first 128GB SSD benchmark looks off the charts, was it done with this board? Seems like there might be some caching going on.
Using NVME on X58 from my research seems doable and not hard unless you want to use it as a boot drive, here's a tutorial I found but didn't get to do: https://mrlithium.blogspot.com/2018/04/uefi-booting-nvme-on-x58-project-w.html

ChineseStunna I think the RAPID setting from Samsung Magician was doing all the caching. I disabled it and got more real scores. Now looks normal? It was done in this system yes (asus P6X58D Premium). It's also connected to the SATA 2.0 port. I also have a SATA 3.0 (marvell) but i don't know if it's better... i think not.
Regards.

Ah yes that makes a lot more sense and numbers look good. From everything I've read the marvel controller sucks on this board and perform worse than the SATA2 ports off the Intel chipset

Hi all!
- I tried the SATA port 3.0 (Marvell) for the SSD and got a little bit better results in read tests and and some even below at write speeds... I think it's maybe a little bugged the controller... It takes much more time to load to windows and sometimes it got some jitters when moving arround windows or something. I reverted to the INTEL 2.0. In the real world I don't really see difference besides more stability in INTEL one.

- Meanwhile I got my X5675 yesterday! Time to do some tests. Installed it all OK.
- In BIOS i could see some diferences regarding W3680. The W3680 had option to change the turbo and cores max multiplier, which i've tried but didn't do much, or I don't know how to... TDP is now 95W (X5675) instead of 130W (W3680). And multipliers in X5675 goes from 12X to 23X (Turbo 25X). There's no 24X.
- For me, I went straight from my stable 4.0 with the W3680 (settings in post above) to the same in the X5675. Then for the 4.2 with 1.3v Vcore in the BIOS. Tested it and drop it until it become unstable = 1.270v~.
- Now i'm @ 4.2 Ghz with 1.296v MAX and going strong with all my usual tests/games!

- So conclusion (for now): The X5675 got to 4.2 with the SAME voltage as the W3680 and with lower temps! Right now i'm doing OCCT and max temp. is 50ºC. in IBT got me to 68ºC tops. Idles @30ºC. My case is NOT OPEN! Just for the record. Just upped the fans for testing. I'm using 3 more fans besides the CPU cooler.
- I think this chip is bit better overhaul in comparison of the W3680. Maybe lucky or the 95W giving some edge here I don't know...
- In the future will test it to 4.4 and see... I think I got som margin left from Temps. and Volts. In the W3680 I could also get to 4.2 but it required me around 1.35v+ and to daily use it got my fans to blow a little bit more and the noise it's not wotrh for me.

4.2 Ghz - 1.296v MAX read in CPU-Z - Vcore ( Multi X21) using offset voltage (+ 0.2250v).
BLCK = 200
North bridge = 3200 Mhz
QPI/RAM (VTT) = 1.25v
PLL = 1.80 (stock)
IOH = 1.10 (stock)
RAM (12Gb+6Gb Ripjaws)- 1600 Mhz @1.60v 9-9-9-24 1T
LLC = Enabled
C-STATES all enabled + SPEEDSTEP on
Temps in around 50ºC MAX while gaming and 68ºC peak while stress testing. 22ºC room temp. Idles @ 30ºC tops.
Cooler = Noctua NH-D15.

Nice RiCK!

If you want NVME on x58 for boot you either have to find an older samsung 950 pro drive or similar with legacy boot, or using a boot loader on another device with something like Clover or DUET.

Here's my usual settings for the last several years lol:

4.2 GHz, 1.272 V
BCLK 200, CPU Multiplier 21. Speedstep on
QPI Link 3600
*QPI/RAM (VTT) = 1.25v
*PLL = 1.80 (stock)
*IOH = 1.10 (stock)
RAM 3x4gb Mushkin blackline - 2000 MHz 1.65v, 9-11-9-27 2T

* I think those are correct voltages for me, I'll have to verify.

averaging ~54ºC at full load without maxing out my fans, custom water loop with a triple radiator. ~23ºC idle with the CPU throttling
