Changed Mobo, crappy GPU oc?

Toto123456

I just changed my motherboard and case from atx to itx coz i travel a lot so i need a smaller form factor.

I was able to oc my 970 gigabyte g1 to 1530MHz on a MSI Z87-G45, and now only 1503MHz on a gigabye Z97N gaming 5 itx, and sometimes my gpu throttle to 1490MHz and getting some artifacts.

I used the same settings as previously used on a msi motherboard. Although as weird as it may sound, my temperature on my itx case was better than on my 760T lol ( only like 4c better) it was around 72C.

Is atx mobo better than itx mobo when it comes to overclocking in general? Or i chose the wrong mobo?

It all depends on the VRMs

mobo dont affect performance

 

when you change mobo did you reinstall your OS?

 

driver updated?

Yes I did, fully re install my system and downloaded the latest driver from the manufacture

you maybe pushing too high OC previously

 

so it getting damaged and thus the CPU cant hit the old clocks

 

you either go higher voltage or lower your clocks

read carefully

 

he was hitting 1530MHz previously

 

now only 1503MHz

snip

did your CPU speed change e.g. did the core clock change because when i overclocked my old 8350 i could not go as far on the GPU or vice versa can not remember

No, still the same, i used the exact same settings on my cpu for both mobos however my gpu results are quite bad. I cant even get stable 1480MHz compared to 1524MHz, that is pretty huge different. My voltage on gpu are also adjusted to max settings already too (87mV). Anybody here can help me out?

Wat.

OP was able to hit 1530MHz with his ATX motherboard, but only 1503MHz with the new ITX board. The graphics card has NOT changed.

Check yor GPU temperatures again; keep an eye on the VRM temperature reading.

I dont quite see how switching to a more compact motherboard will give lower temperatures -- it is usually the direct opposite.

"MoBo can and does affect OC since it's delivers 75 watts across the PCIe bus and if that power sags and dips it does affect performance. How good the power circuitry is on the motherboard is almost as important as how good it is on the GPU.

There are also other minor issues between boards like what kind of system links PCIE to the CPU and how fast that is (how well hyper transport is working on AMD for example) etc etc...

Even PCIe frequency variation can affect OC to minor degrees.

So yes, different boards will give different GPU speeds." 

 

It may be a minor dip but it's still relevant considering OP went from a ATX > ITX this can indeed happen.

Yes the above is true, when you have several graphics cards installed in a single system. For an example, from your quoted source, the individual is referring to a bitcoin mining system with three overclocked HD 5850's in one system. Having owned three HD 5850's in the past, they can draw a lot of combined power. This is also why more and more motherboards have an extra SATA or 4-pin Molex power connection on the motherboard, near the PCI-E slots -- to provide more power when more GPUs are installed.

 

An example is my ASUS Crosshair V Formula motherboard:

Directly from the motherboard manual, page 2-27.

" EZ_Plug...Connect the 4-pin EZ_Plug power plugs to ensure sufficient power supply when you install multiple graphics cards."

The PCI-E frequency will oscillate -- it is not exactly 100MHz -- as it uses a crystal oscillator IC on the motherboard as reference. Even so, the variation is very little, typically well within the range of +/- 1MHz. These oscillators use a Quartz crystal, and usually have a Quality Factor of 50,000 (10,000 when a load is attached) or more -- they are very accurate.

 

 

The communication bus between the PCI-E slot and CPU will have some effect, I agree, but frequency used / set by the CPU should be enough so it won't hinder performance significantly. This will vary depending on the CPU used.

 

For an example, back with my Phenom II X6 1090T and 890FX motherboard, increasing the CPU-NB speed showed improvements to the DRAM read / write performance, but that is increasing it from 2000MHz up to 3000MHz -- a full 1GHz bump. With my FX-8350 and 990FX motherboard, performance gain started to level off, to where there is little to no performance gain, when the CPU-NB climbed into the 2400MHz, 2600MHz, and 2700 MHz range.

so you went from (i'm assuming) a mid tower, to an itx case and you are wondering why you aren't getting as good of an overclock?

 

if you did go to a smaller case the reason is quite simple. insufficient air flow. which is always more restricted in an itx case. it is hard to keep an itx case well ventilated.

My rig:
CPU: i5 4690k 24/7 @4.4ghz (1.165v) Max 4.7ghz (1.325v) COOLER: NZXT Kraken X61 MOBO: Asus Z97-A   RAM: 16GB Crucial Ballistix Tactical   GPU: EVGA GTX 970 SSC   PSU: EVGA GS 650W   CASE: NZXT Phantom 530 HDD: WD Caviar Blue 1TB + WD Black 2TB

The temps are better on my itx case as the gpu is sucking the air dirrectly on the side panel because the gpu is vertically mount. My gpu is running at 66c or even 63c at full load if i turned on air con in my room. So to say that the temps are bad and is a factor limiting my result is near impossible

i just don't see how it could be the mobo but if it isn't temps then i don't know. i really don't think it could be the motherboard. contact gigabyte about the motherboard however. it would be your best bet at this point.

maybe try messing with the PCI-E speeds and also updating the mobo BIOS

 

does your GPU have a Dual BIOS switch?
