Hi guys and ladies,

I've got a little problem:
I just recently bought a dx58so with 12 gb of ram (3x4) and replaced the i7 920 for a x5650. Now i'm trying to OC this cpu but my ram is doing some weird stuff, Im only able to run it on stock settings even the XMP-settings won't work. after a lot of research and some trial and error the following setting would boot also:

16 uncore / 6 core multiplier (16 can get to 20 but moving 6 to 8 will make it unstable although the memory will only be clocked at +/- 1300mHz)

afther that the following settings (top to bottem): 9-9-9-24-140-(5-10-5-5-40-20) (tCL-tRCD-tRP-tRASmin-tRFC-tRRD-tWR-tWTR-tRTP-tRC-tRAW)
From the last 6 numbers (in brackets) I only changed 40 from 32 (if i remember correctly). but the 5th number (tRFC) looks pretty high to me (it's at its maximum), but chaning it to 130 makes the ram unstable (again). the first 4 i just set to stock but was 8-8-8-20 when put on auto. The voltage is 1.54v (stock if im right) and QPI 1.275v stock 1.150 (but not 100% sure). when set command rate to auto it will run 1t (2t not tried).

bclk is 182 4.19gHz with 1.3V (1.275 with CPU-Z) and max around 63-65 degrees (MSI afterburner). 4.4 wil get me almost 75 degrees. cooled with hyper 212X and two fans.
mem: crucial ballistix sport 1600
At 1.1mhz because like above stated multipier to 8 will make the system unstabel also with 1.62v.
IOH is at 1.225v

my questions any setting i've set wrong (fist time bclk overclocking anything)?
What voltage can i savely run QPI and IOH on and what do these settings mean (that's the reason why i stopped because i dind't dear to get those higher)?
The heatsink besides my cpu is getting pretty hot also with the small blue LED fan installed, is this normal?
And can you help me fix my ram issues?

I'll try to post some foto's tomorrow, if i spelled something wrong or made some grammatical mistakes or something is not clear (or also typed wrong) please let me know (I'm not a native English speaker/nor writer ;-). I hope I've found the right place to get some answers and this is the right place to ask these questions, if not I'm really sorry.

Kind regards,
Techninja.

P.S. I did my best to research most of these issues but most of the oc-guides don't seem to apply to this mobo because of different names and settings in the intel bios (at least thats what it seems like to me).

 

[agent_x007]

QPI max is 1,4V (Intel spec sheet).
But you shouldn't need that.
Values between 1,3-1,35V will be fine for 24/7.
IOH can get toasty around 1,3V, but voltage wise it can take it no problem (if it's cooled properly).
Cooling is the biggest problem in IOH case. If it's hot (70C+), you reached your safe voltage for it.

As for stability :
Q1 : What is your NB/Uncore clock ?
Q2 : What is your QPI clock ?
(use CPU-z to check those)
Also, can you upload a screenshow of CPU-z's "SPD" tab ?
It will show us exact RAM you have.

AUTO settings confusion :
DRAM Frequency of 1333MHz is max that will be use, because that's the official limit on Xeon X5650.
It's also the reason why you get CL8 on Auto timings (lower frequency = lower timings as standard, as saved in SPD profiles).
If you want more, you have to set it yourself (with DRAM Frequency, first four timings + Command Rate and memory voltage).

Damn, so close to that 1100CB....Im gonna get it one day

PS. Where are those 6 core Raisins (Ryzens) now, lol

Rise+Zen - Ryzen, that's the way I'm reading the name. AMD sure weren't referring rye bread with the first part.

 

[Techninja]

I was wrong about the 4.2 and 185 bclk it is around 175 now. Because the 4.2 oc was running pretty hot (75C).
It's running +/-3.85 and +/- 4.0 boost. I hope this is the right info to help me.

thx for everyone that is willing to help me out,

Welcome to the Xeon Club @Techninja.

 

[johnspack]

Ah frig! Thought I had no usb3, finally re-enabled it with legacy usb3 support off, works! Anyone moving up to x79 should watch for that. I really wanted those 4 usb3 ports in the back to work.....
And welcome Techninja, I just finished over a years use with a x5650 powered system, I really enjoyed it. They do produce stupid heat, and in the end with my NH-D14 cooler stuck to 4.0ghz.
Same cooler on this cpu I'm at 4.7 24/7.....

 

[Techninja]

Thx a lot though my temps are 62c on 4.0 but Deen tot rocket when going tot 4.2. Does anyone know the max temps that are reasonable for daily use? And would a i5 6500 be An upgrade or a downgrade i mean most new games seem tot be able to use more cores?

hi guys, new here... and looking towards my 1st build. i want to build a workstation that has the fastest possible I/O, GPU power, and CPU power for when H264/265 encoding can't be done on the graphics card (depending which card is chosen, of course).

the main purpose of the workstation is video post-production including editing, grading, vfx in 4K and lower. with the possibility of significant upgrading when necessary to accommodate 8K workflow. the 2dary purpose is that of DAW (digital audio workstation).

my problem is that there are so many different types of Xeons to choose from, i got no idea which ones to go with, not to mention the mobos.

since a lot of storage needs to be accessible from the CPU and GPU, do you start by looking at mobos first and select those that offer the maximum number of I/O lanes for M2 and U2 NVMe drives?

or do you start with the mobos that allow dual-CPUs?

i am assuming that at the high-end, mobos will have at least 2 or more PCIe 3.0x16 slots for multi-GPU setups?


and what about OCing the DRAM and the CPU? what does one need to consider here? VRMs and how many voltage phases?

thanks for helping the noob amongst you.

 

[Techninja]

Also pretty noobish certainly because i mostly game but won't the new ryzen cpu's fit the bill if you want possibility to upgrade?

 

[johnspack]

Of course they might. I am closely watching Ryzen.
I'll tell you the gods honest truth... I want ryzen to deliver.
I ran amd cpus since the amd286. I hated going to intel after the
athlon64 x2 to core2duo thing.... I so want to come back home!

 

[Techninja]

seems like after the last bios update the performance has been increased dramaticaly

not sure. i think that depends on on the mobo.

 

[__isomorph__]

could you please define 'dramatically'?

 

[__isomorph__]

Of course they might. I am closely watching Ryzen.

yeah, i hear ya. but after reading this post from user L'Eliminateur on this board : https://www.techpowerup.com/forums/...ks-at-memory-speed.231585/page-4#post-3623645

am not so sure anymore. and after checking the Xeon prices--had no idea Xeon was that expensive!--looks like an i7-6900K might be a better choice. but the Z270 mobo doesn't offer as many PCIe lanes, and if i am not mistaken, not quad-GPU , but only 2 GPUs over x8. so perhaps save money on the mobo and CPU and spend the saving on 2 Radeon Duo Pro? is the 16TFLOP rating for real?

why the hell is this CPU release so confusing?! i changed my mind again and am unashamedly making a 180 after viewing this vid:

the numbers speak for themselves. i am now convinced Ryzen is the beast to tame. add to that an AMD Radeon Pro Duo (2x 8GB R9 Fury X GPUs GCN v3 Fiji architecture for a total of 16 TFLOPS single-float) and perhaps another one for 4 GPUs in 2 PCIe slots) or wait for whatever monster the VEGA cards will unleash upon this godforsaken planet, and well... we got ourselves like what seems a fairly decent system capable of real-time 4K video edition and 3D rendering.

 

[johnspack]

I think Ryzen will end up making us really old amd fanbois proud..... I just have to oc my sb-ep to the bitter end, just like I envisioned it!
Wow, that looks worse than it should, heheh!

Hallo everyone again,

First thanks to Biffzinker for welcoming me and agent_x007 for your replay.
beside that here are my bios setting right know:




The problem as stated before is the ram it will say in bios and in cmd that it is running at 1051mHz although CPU-z (post above) will say it is running at 700 mhz tripple channel. This is pretty confusing to me. 175x6 = 600 + 450 = 1050 mhz ? The other problem arises when a multiplier of 8 (8 x 175 = 800 + 600 = 1400) will make the system unstable even with a voltage of 1.64 (or 1.62 not sure). Anyone who knows (or partially) what is going on it would be really nice to give me a hand with this problem. i'd appreciate it very much if you could find the time and will to help me.

Regards,
Techninja

You are not the first user to have problems with memory multiplier on this board (DX58SO).
I guess it can be a BIOS bug, but I can't be sure.

Easiest way to find out if memory is running at 1060MHz or 1400MHz, is by checking memory bandwidth in AIDA64(Cache&Memory benchmark)/SiSoft Sandra/MaxxMEM2 :
1060MHz @ 192-bit = 25 440MB/s
1400MHz @ 192-bit = 33 600MB/s
If you get 25 440MB/s or more on memory read/copy, it means you already have 1400MHz clock (just as CPU-z suggest).
As for "8" mem multiplier instability : If in reality it's wrong by +2 (just as 6 multi can be), it's normal it's not stable - "10" would give you a memory speed of 1750MHz.
Try to set higher timings or higher memory voltage (just as if you wanted to run 1750MHz).

EDIT
My scores @1400MHz

And 1060MHz :

 

[Techninja]

I don't think 1750 would be possible (1333 is max on this bord without oc of im right?). Thanks a lot for the tip about AIDA64 tried tot find such a programm but couldn't find one so i tried cmd but this seems tot just copy the bios. Thanks a lot for possibly the missing piece in the puzzel. Thanks a lot for your time and effort agent_x007.

Regards,
Techninja.

I can barely contain my excitement, one of these is on the way. Super cool and super rare. It is the basis of a build for my son. Hes not quite as excited as me but he will be when he sees this baby roar.
