Not a bad score for 4.3 but I would have expected a little higher with 3200. You might find you've dropped off going that low.

You might find better performance by raising either TRRD or TFAW. By having TRRD that low you're creating an additional delay between banks.

This is what TFAW does. This can never be lower than TRRD x4 anyway, but I would maybe try raising it. TWCL at 9 is pretty damn low also, try and see differences with different means with this set to 13 or 14.


No promises just see what works best. I score @ 4.375 1770 with 3000 C15 with Command Rate 2. Sometimes it's best to leave these things alone For benching though, C13 3200 is a damn nice place to be

I'll keep fiddling and experimenting. Finding that more enjoyable as i can't seem to get into any games at the moment.

For now though I'm going to spend the day in the pub eating and drinking.

Thanks Matt, and don't worry - I was only going to use as a rough guide to where I might start from.

Cheers, Merry Xmas.

yeah there isn't much out, saving Unity for Christmas but enjoying Dragon Age at the moment. Just won GOTY as well

I've got my 5930 running at 4.7 just by changing the multiplier, voltage etc is all on auto settings on the Rampage board, my memory is @ 3100 and as a complete noob guess I should be satisfied?

Temperatures are lowish but guessing if I were to push for more I'd have to be a lot more hands on.

CPU voltage is 1.344 which I think is okay, supposing there is nothing stopping me trying running a bit faster with little more voltage?

Great starting point for sure, you can leave system agent voltage alone if the system is stable but check how much the board is overvolting. Any more than 1.15v is excessive. I wouldn't go far over 1.35v depending on your cooling

 

[quonker]

Thanks for the reply.

It seems completely stable and is holding at about 1.35 to 1.36, running cool as well so will just leave as is.

I've got a Cooler Master Nepton 240L which seems pretty good tbh.

 

[Silent_Scone]

Get to work on cache now then

 

[quonker]

Well that's where I am out of my depth lol

Will look for some guides

 

[Silent_Scone]

start with manual voltage and try 4.0 at 1.3v and keep increasing multi till unstable.

After 4.4 things get tricky. You may need between 1.35-1.45v

 

[quonker]

Running now @ 4.8 with my cache at 4.4, runs really well and temps are low but it's more difficult now to overclock my 980's using Precision X.

Get crashes if I try overclocks that work at stock cpu speeds, or at least with overclocks that are less extreme.

GPUs are not running overly hot, late 50's

Is this something I should expect?

Is there anything else I need to tweak?

 

[Richard-h2]

Quick question ...

So we change the multi up .. does the cache need to be the same or just a matter the more you push both the better ?

The cache speeds makes little difference. Leave it at stock

 

[hell_r@zer]

uncore really is just much ado about nothing.

raising voltage on other sections of the core really doesn't do anyone any favors other than raising temps.

 

[Silent_Scone]

The cache speeds makes little difference. Leave it at stock

there are performance benefits from raising cache. Especially if one is able to match core frequency. Uncore is very much tied to memory write speed, so by not raising cache at higher dram frequencies you are selling your system short.
It's best to leave cache tuning till last however, should only take a small bump in SA and vcore, sometimes not at all after dialling in a stable cache / voltage

 

[quonker]

Still have issues with my 5930 overclock.

Not so much issues with the cpu itself but the impact on overclocking my GPU's

My system is rock steady at 4600 with cache at 4000 and dram at 3100 but I can't overclock my 980's at all without the system locking.

Is there something that I can tweak to improve this?

My gpu's overclock nicely when cpu is running closer to stock.

Running cpu @ 1.346 and cache @1.22

Any help gratefully received.

That's a strange one got my 970 in sil 1500 boost/2000 memory running the cpu (5930) 45core 45cache with no issues. How are you overclocking the GPU`s

Can't overclock at all which is annoying, 3dmark crashes even if I move the GPU clock offset by 100.

Doesn't crash and is very stable at gpu stock speeds though.

Are you overclocking your CPU using a strap or changing the BCLK?

 

[quonker]

Using the BCLK @46x100.

To be honest not really sure which would be best or even if there is a difference.

 

[uksoldierboy]

I noticed when overclocking my 5820K, using anything other that 100mhz strap really screwed up my gpu overclocking.

@4.6 now just using the multiplier and my card is happily running at 1540-1550 24/7.
