Aren't there 500 BIOS settings in this thread already?

[LuckMan212]

I also had trouble going over 265, and I was able to push to ~272 memtest stable for 20+ loops using the following settings.. you might want to try them!
Using these I get ~7100mb/s bandwidth in Sandra

G.S Technician Hi,
Welcome to the USA and the Forum. I personally dont own any G.Skill yet, but if your company is making a great effort putting someone like you on the firing line you have my Respect and Interest. You mentioned free photo uploads. Ive tried a few and the best luck Ive had so far is Photobucket. If these Ballistix I have dont work out, then maybe G.Skill will. OMG, I just saw the Date on the first Post hahahaha.
Good Luck.

Hi, I've also recently got a set of HZ's and I'm also having problems getting it to pass memtest at anything over 265mhz, been over on kakarotos thread and tried quite a few different vdimm settings but to no avail
I had high hopes for this ram as I've seen quite a few people get near to 300mhz, all I want is 270 stable.

these are my past posts to fill you in...

I don;t have screen, but key settings are 9ns max async and 7ns read preamble.

Drive strength 6 and Data strength 2.

Kakaroto, I've tried those settings and as soon as I set read preamble from auto (5.5ns according to a64 tweaker) to 7ns my system actually fails to post!!

if I run the rest less the read preamble timing, it will end up getting more errors in memtest than when the settings were on auto.

I'm stuck at 265mhz and would love to get to 270mhz. ram is running 2.6v. I really thought these sticks had it in them

this is my setup....

I just got my set of HZ's, and there limit resides at just under 270Mhz 1:1 with my 146 opteron, I'm using the dram settings Techpowerup used when overclocking there hz set.

I'm using the 623.3 bios, can my dram settings be tweaked further more? I'd like to get it stable at 270fsb.

Cheers

edit: it will alway fail dead on 40% in memtest. I've raised the vcore of my cpu even though it is stable at 3ghz with less voltage and I've also ran it at a low 7 multi, but still the same erorrs

I really appreciate any help

Thanks, I tried your settings @1:1 240 would boot 2.5v.
Then tried @245 2.5v/2.7v/2.8v would crash loading into windows.

I'll stick these settings. My memory is gaming stable @265 2.5v 3448 9/10 divider. I was able to run SuperPI 32m @270 3448 which was posted couple of months ago.



superPi 1m @275 2.5v

that's a nice 165 you got there! 2750 at stock volts!
what stepping?

CCBWE 0550 UPMW 1.4125 vcore is close to stock which is 1.35v.


I used clockgen to reach 2806 Mhz at 1.4125v. The highest speed it boots into windows is 2700 Mhz 300htt, but 24/7 stable at that speed.

I only get to 256 Mhz (STABLE) with this memory

Can it be the memory controller on my (OLD) CPU (Winchester) ?

it might be somewaht related

[Krohling]

What about these settings in BIOS, which do you use?
- DRAM Drive Strength (Level 1-8)
- DRAM Data Drive Strength (Level 1-4)
- DRAM Response Time (Normal, Fast, Fastest)

I was used to pick Drive Strenght @ Level 7 and Data Drive Strength @ Level 2 for Samsung TCCD. But I don't know which is "most recommended" for these G.Skill DDR500 2GBHZ as they are Samsing UCCC.

Response Time I never changed, always set to Normal...

Which Ultra -d bios for a new Opteron 165 and HZ install

[Okda]

704-2Bta is the best

Hi guys
First Post Here

Get my pair of these mems a couple of days ago and test a little

Got DDR590@2.76v But not stable
DDR560@2,56 3-4-4-8 Stable
DDR550@2.52 3-4-3-7 Stable

Pic of DDR590 and some of another testes in Everest
I'm a brasilian guy, so, where u see "Escrita"=Write, "Leitura"=Read and ''Latência"=Latency :p




Some advice to use it whit my opty 144 ang get the most stable performance? Div 10 should be best for me, but 144 multi 9 sucks couse my opty does 2800Mhz vcore default, but 9x280@200Divider (poor performance for my max mhz) versus 9x312@183Divider (Cant get sability on this ) versus 9x343@166Divider (where i get 280FSB but the opty cant reach it stable.

Anyone whit a opty 144 and this mems to get me a little help??

HI, I have 2x 1gb APACER UCCC 2.60v and I dont know if it its working normal at the moment. Can someone tell me the right timeings so that I can make the CPU to work on 3.0GHz http://img301.imageshack.us/my.php?image=ram7lq.jpg

so I could subscribe to post...also wanted to know what you are stting tref value to,to get 100mhz 1.95?

thx that's what I thought but was not sure...am able to run at 280 1:1...

hey all,

just got my HZ a week ago now, and am quite happy with the performance.
so far have got it to 265mhz 3-4-4-8 1T @ 2.7v, running 1:1 (memtest stable). this is fine.

but unfortunately, when restarting my PC (or when powering on again after shutting it down), 9 times out of 10 the CPU multi has set itself to x5. this is no fun lol.

i have to enter the bios every time i power my PC on, and set the multi back to 11. even then, the system wont post and i have to reset and do the same again before it will post at the correct speed (weird, huh?!)

i did not have this problem with my old ram, which was 2x512 of Corsair XMS 2700 LL, and has only come since i upgraded to the HZ (some upgrade lol, DDR333 = eugh).

ive been following this thread for a while now and have read it all, and so far it appears noone has run into this problem. has anyone heard of or experienced anything like this before, or can suggest a solution?

cheers guys,

ER

(mainboard is Ultra-D and CPU is 3800 venice if this helps. running 260x11, 1:1, HTT x3).

Hi all, this is my first post here.

I think you have a power problem
What power supply you have ?
My friend got the same problem as you, e has a 300W power supply and is PC always started at lower clocks.
I change is PS with an 400w and

My HZ are at this moment at 250Mhz 3-4-3-8 2.6v
I start at 3-3-3-8 2.6v, but i got 2 errors on memtest (Test3)
I need to check this out, some help to get that chip at 250Mhz 3-3-3-8 please?
