AM3 RAM OC?

[Bullant]

Just tested another 955 CPU and imc better, on water CPU... mem 940 6-6-5-16-11 , 1.77v. The mem seem to scale dram volts a little more, compared to my other chip, on water the core and uncore not as strong tho

Hey my board doing that fail boot thing too. So fun to pass pi then fail to boot when you restart and need to clear and reapply Saber tooth 

It's a complete POS board, is terrible for maximising CPU's on cold, for some reason it limited me be nearly 800MHz max clock (FX-8350) on both boards I tested compared to a CHV.

[Bullant]

Did a little eff testing today on the 955 amd, is ran on single stage -30 and memory are 1.83v set bios....will run on ln2 next time refill, should see good boost when push the uncore more

 

[Bullant]

Was testing PSC other night on 1090t a fail run on loop 5.... the couple runs I tried.The cpu was -50 and memory -30, memory will tighten up more but seems imc related issue on the freq side. Given little more time should improve, will try more cpus and boards as I find them within my budget  ahahah

Yeah I wouldn't expect too far above 2100 on thuban IMC

I'm curious to hear why your tRAS and tRC are so loose - is that what it took for your memory to pass 32M @ 940, or is it just faster? I was running 18-11 recently, but that was around 880 MHz.

[Bullant]

Bit of both, that imc not the greatest and I dont see real big gain dropping lower then what I am, so I rather the extra MHz over dropping them little more 

 

Even when I can drop down to the "11" it's worse for me, or not worth it,  I try to use all that I see as a guide only and run what is faster for me. Was like haswell how some others see gains in couple of tighter subs , I didn't. I found the same with PSC on sandy and ivy, below tras 21, like 18 was bad for me 

Ran this one much the same tho little more mem MHz .Its the only really hyper I've tested or used, so I can't compare mem

Nice job @Bullant, AM3 looks like a lot of fun! Long time not benching really want to benching something. And i have same experience, tras 21 is faster on sandy than 18 or 15, tested on samsung and psc.

You should do it Speed, its slow but same for everyone lol Its also cheap is what I like ahah

To be honest, looking at country cup scores, @Bullant is the only one with a nice efficiency in 32M.

[Bullant]

Thanks for the kind words @I.nfraR.ed hope to see you benching amd soon also 

[Noxinite]

Nice Bull.

I never figured out why my score was so slow. When I rebenched for TC I tightened RAS and RP and knocked off 6-8s, but still not good.

Board. Most people were benching on non-efficient boards, some even on an awful boards for Deneb, e.g. Sabertooth or M5A99X.

I was expecting some LN2 scores from you, though

[Noxinite]

Is it required to only bench AM3 on Giga boards then?

I tried some LN2 for TC, but only on 939 32M. It didn't go well, so I gave up.

[speed.fastest]

No, probably that mean 790FX/890FX is needed for Deneb/Thuban. 990FX/990X for FX. Probably its true because 990FX not good for high HTT on older CPU.

Hopefully can comeback soon

Practically - yes. But not every board and not every revision. 890 ud5, ud7 are good, some of the 9xx boards too, but I think it greatly depends on revision and we know Gigabyte has ton of them... My 990FX-UD3 rev 3 is the worst board I've ever had. From Asus - Crosshair III. Not sure about other brands. Crosshair IV isn't bad, but still slower.

The board I am using is very tricky with awful vdroop and only good for single-threaded benches, not really suitable for multithread like Cinebench and wrpime.

[Bullant]

Tested a 960T and 990Fx UD3 tonight, cpu SS only about -25 because no Paste lol....is why couldn't get any higher NB Freq. Hypers @1.85v...will run this again later on the 890FX UD7

 

This board is rev 1.1

I guess it is a non-uefi board.

890 board is the ticket for Thuban and Deneb.

Older revisions of 9xx giga boards are surprisingly efficient (non-uefi bios). Not sure if all of them, but at least some.

I actually have that board, it was efficient for me too IIRC. But I managed to get plasticene in one of the ram slots, so now it doesn't clock ram very well.

It does have uefi option in bios, I seen it...I've not touched it.This is little new to me, if it has that option in bios is it a uefi board? I'm at work now so can't look at it to post a pic, when home I'll  look again to be sure....unless you know what it is?

Yeah 890 seems good, thanks mate.....I'll run it up again on my 890 ud7 soon

They have the old trusty Award bios interface, while newer revisions have the new flashy, slow and buggy graphical UI where you can also use mouse.

[Bullant]

Oh I understand now, it makes sense why those ones would be slower then...thanks 

[Alpi]

My 990Xa-ud5 outperform CrIV in all 2d benchmarks. The gap is not so big but ud5 shows that in every benchmarks where I saw.

I guess some memory settings can be the main reason.
