***Intel i7 4790K Owners thread***

If buying a large cooler like 140mm (possibly some 120mm) Noctua, look up their site and see if it will block your TOP Primary PCI-E 16x slot.

They are going to address this and ram clearance with offset models soon (were shown at show a few week ago).

My Z68 ROG was E-ATX so fine but this Z87 ROG is normal ATX so top slot is block meaning I need to use the less than ideal PLX 16x slot and SLI is basically a no go for now.

I did check this on their site, no issues with the Gigabyte Gaming 7.

Anyone know what the voltage setting for the cpu that affects memory timings? I am stable at 4.7 with 1.24 volts. I am now trying to run my memory at XMP. But it causes a BSOD in the stability tests.

Wondering if a small bump up in a voltage setting might help. I just don't know which one.

Using a ASUS Maximus VII Hero board.

Thanks

system agent voltage I think

Only tested this to 4.6 so far as im having to bring voltages really low to keep it under 80c

So 1.2v at 4.6



I think i can go lower with the volts but just need time to do more testing at the weekend.

If I leave volts at auto they default to about 1.35v

Running on the Asus Hero and the chip is L331C518

Decided to just run at 2133mhz. Seems stable. After an evening of overclocking and stress testing I have hit 4.7ghz stable at 1.24v.

Will see if I can get 4.8ghz stable over the weekend but to be honest I am happy with what I have got .

A comparison clock for clock

2600k @4.6



4790k @4.6

same ram/timings?

try cinebench r15

 

[Coolasmoo]

Yep same Ram and on the same Windows 8.1 installation.

your physics score seem low to me on 3dmark for the 4790k

could be ram speed your using idk

Just 1600 on the ram

 

[wazza300]

ahh,bout right then,youd score above 13k imo with faster ram,2133mhz-2400mhz

For comparison, on skydiver my physics score is just over 13100 iirc, cpu at 4.7, 780 @ 1189/3305. 27500 overall score. 953 in cinebench.

 

[wazza300]

I score 12950 with 3770k at 4.8,ram at 2133mhz

your cinebench beats my 4.8ghz score easy tho

On the 4770k @ 4.5, physics score was 1200 something, 911 in cb. Currently have the 4790k back running at stock though.

why have you gone back to stock setter?

 

[setter]

Gonnna wait till i get new paste on the cooler and start from scratch as my previous settings weren't just right. At least its a baseline though.

 

[PCZ]

Tell me it isn't so !! Yes that is an H87
I will see if the voltage can come down, never expected it to work.

 

[Canary Wundaboy]

I'm disappointed now that I've received an L3 chip but I'll reserve judgement until it's in the rig and clocked, I don't need more than 4.6GHz anyway.

 

[cwgk91]

So all the L4 chips seem to be getting better clocks? Sadtimes

Suddenly it feels like a good idea to wait a couple of months before buying... Be interesting to see if the later line is subtly different.
