Hello, first time posting here brows.gif
changed from vrz to here because vrz amd thuban oc thread very "cold" sweat.gif
1st question:
how to test 8GB ram by using prime95?
the default blend test only use up ~40% of my ram,
now trying the custom stress test but really no clue how to set:

is it correct? doh.gif

welcome onboard bro, glad to see u here. vrz is full of intel fanboy...  tongue.gif

for blend test, i always use custom with:
1. min fft @ 8
2. max fft @ 4096
3. memory to use at least half of ya total ram size
4. time to run @ 1 minute

*cpu test is 8-512k, so if i want a quick test on ram only, i'll use 1024~4096. dunno how accurate it is but i'd say blend test is still d safest way for all components stressin.  smile.gif
yup, i'm aware of that. looks like kingston still maintain d tradition of given out good chippies on kvr, just that it's more confusin this time coz buyin relabeled chip sticks can be 2 edge sword, if u get good chippies then voila, but if d chippies are alibaba, then...  cry.gif

something value but no so value (around 50% more expensive) than kvr. keep guessin... btw, i really miss my old 1055t, this 1090t is makin d eco 1333 & its compatriot looks like normal ram.  sad.gif

Stressed with blend with custom stress setting for many time already, and y-cruncher afew times, i think stable liao

best ram i ever have rclxms.gif thought on amd platform the ram need at least 1.55v to run properly.

great timing indeed.. may i know what vdimm used?

i used the same speed binned eco..
can do CL6 1600mhz with only more then 1.65vdimm

1.55v thumbup.gif
any lower will get BSOD lol.
need to test more i think, just got "FATAL ERROR" on prime95 stress test lol doh.gif
only rounding error, no crashing on gaming, bsod and ramdom lock-up yet sweat.gif

When overclocking non-BE cpu, you have to take care other part as well.
if you are raising HTT, eg 210,
HyperTransport clock, Ram clock, northbridge and your cpu clock will raise as well.

experienced ppl usually will make large jump on HTT clocks, eg 250/300mhz,
then decrease the HTT, NB, RAM multiplier so they will run @ stock speed.
do this only if you want to oc your cpu.

oc black edition cpu is much easier tongue.gif
because you only have to adjust the vcore and cpu multiplier.

Is MSI 870-G45 a good overclocking board?
*
Missing MOSFET heatsink, and looks like only have 4+1 power phase.
the MOSFET temp will increase alot if overclocking + 24/7 usage sweat.gif
this board use old AMD 770 chipset, not the 870.
thought i hear ppl say more powerpahse and MOSFET with heatsink installed will help increase overclocking stability.

870A Fuzion Power Edition <- 870 chipset thumbup.gif
870A Fuzion < 770 chipset.
may be cheaper: 890GXM-G65
im not very familiar with MSI, only Asus and Gigabutt mobo sweat.gif

Wah many low end mobo do not have MOSFET heatsink one, overclocking sure make the MOSFET hot till can boil water liao.
review for the 770T-UD3: http://www.xbitlabs.com/articles/mainboard...70t-ud3p_4.html
i love how giga make the board, they leave the push-pin hole on mobo, so user can install MOSFET heatsink afterward lol.

last year when i hunt like hell the 770t ud3 not coming out.. only the USB3 that lack of the UD..kekeke
but now i dont even bother about that board
for mid ranged mobo, even the mosfets heatsink are there, i sometimes will take it off, and replace with ramsinks..
why, cuz the heatsink is too thick..and the thermal pads also too thick..

@piumiu..
looking for a mobo also for evo replacement.. hows the oc-ability..ram oc good? bios richness?

@#@#(*$ !!!
this is kunta..
*
Low/mid end board can lah, high end one like 790/890FX, thier MOSFET,NB,SB heatsink is stick together one, it would be pain in the butt if want to remove them.
like this guy did on the 870a ud3, with thermalright heatsink:
http://forums.vr-zone.com/photopost/showph...eos1067&cat=500 thumbup.gif (just scroll down a little)
he even put heatsink on the choke too lol drool.gif
im thinking to replace my mobo thermal tape and reapply thermal paste too sweat.gif
never do that before, afaid will screw up my mobo sweat.gif

1090T now only 329, but i forgot the price when the first launch, 4xx something right?

Aiya play till sien ed, thinking selling away my mobo liao lol sweat.gif

There arent much 2000mhz RAM can run well with AMD if you want the RAM run at the rated speed.
unless the RAM is supported by you mobo.
there are tons of 2000mhz ram only can run on INTEL P55 and X58 chipset.
only the G.Skill Flare 2000mhz is certified to run with AMD/ASUS mobo iirc.
correct me if i wrong sweat.gif

when lowering the timings, we should lower one by one eg 8-8-8 to 7-8-8, and then 7-8-7 so forth. voltage no need to adjust i think.

where are other pros here? brows.gif

Aiya, just use it lah, i think 6 cores + ur good mobo can last u untill bulldozer launch alredy, not like ur using an ancient Sempron there laugh.gif tongue.gif

lol sien liao, thinking going to lower end like Asus 890GX or GIGA 870a ud3. cause i dont need so much pcie slot, duno when can kumpul cukup duit to run Crossfire, or may be PCIE SSD LOL sweat.gif doh.gif
need water cooling but currently very miskin lol, air cooling very noisy dahhh rclxub.gif
the only reason to hold this mobo is, it support IOMMU(not using it anyway sweat.gif ) and 8 sata port lol.

Thanks for replying! happy.gif

so does it mean that my current AMD processor not able to reach 2000mhz even with overclock?
how to check if it is supported by the mobo? if i use ratio of 1:4 with fsb 250mhz it says that the effective ram freq is 2000mhz.. however from what i read on the net, you could only achieve 2000mhz if you overclock your mobo to 4.3ghz like that... which I don't understand because my processor now only 3.5ghz also can reach? or is it we cannot use the ratio of 1:4, but have to use 1:3.33 instead? (which makes sense because if 3.33 is used instead, means i have to increase my FSB till 300, 300x3.33x2 = 2000mhz and processor will be clocked at 300 x 14 = 4.2ghz ? correct me if wrong...)

thanks for the tip for memory timings smile.gif
*
Just checked MSI website, couldnt find any Qualified Vender List for RAMs for your mobo sweat.gif
its more to RAM + MOBO problem i think, there are quiet afew ppl here eg ah koo can OC the ram to run at 2000mhz, you just need a suitable RAM, he now got a pair of Geil 2133mhz ram already sweat.gif
and no, you no need to oc your cpu to 4.2ghz to make your ram running stable at 2000mhz,
1:4 ratio already can do that, any other timing may have problem, eg 6.66x. 5.33x and even at 4.00x, i experienced this before, my mobo will not boot at this ratio if the ram were oc to 2000mhz, only 8x can boot, a.k.a 1:4 ratio.

you can check this thread for reference: http://forum.lowyat.net/topic/1637973/+0#entry37930430
especially the ram with 2000mhz, you can see ah koo only raise the CPU clock to 250.

cute lil girl u have there... number pls.. tongue.gif

i want to ask u guys something..

1:what board can do high HTT? like >350..
not necessary premium board..

2: MSI 790gx gd 65 can do high htt or not? i have one in my possession..but i dont have time to try

3: cloudwan, the C4F can go how far? the HTT?

psst.. i dont have much time to online and googling.. so i need some spoonfeed here..thanks tongue.gif
*
Well i only found Giga board brows.gif
http://www.overclock3d.net/reviews/cpu_mai...-a_ud7_review/4
Highest HTT is 380. < Cosair Dom GT 1600mhz.
Probably depends on RAM. I was able to hit 325HTT when i was using Ripjaws 2000mhz.
now only 300HTT when using ECO 1600mhz, i have yet to oc ram cos my skill is super lousy sweat.gif

another review for reference:
http://www.hardwarecanucks.com/forum/hardw...-review-10.html

870a ud3, max HTT 336
http://www.hardwarecanucks.com/forum/hardw...d-review-9.html

CHIV max HTT 330

my 870a ud3 max i can do is 330htt.. decent enough but i wish for more..C4f just 330mhz eh? isit foreal? i hope the review was wrong.
*
Pretty much depend what you have sweat.gif
i myself only can do 320 for now when using eco @ 5.33x ram multi + 1.65vdimm, the board simply wont boot even if every setting is stock and the ram multi is 4.00x.
chiv can clock better bah, the 330htt prolly limited by the corsair xms 1600mhz sweat.gif

Any Eco 1600mhz user here?
IS it safe to run this ram at 1.65v? sweat.gif
Well Dam hard too boot up the mobo when the HTT is over 300 sweat.gif

It is safe at 1.65V

But if you intend to push the volt higher,make sure you have proper cooling on it smile.gif

Well no active cooling sweat.gif
cant install any ram cooler cos blocked by vx doh.gif
only 2 noctua p14-flx as exhaust. I need some 1900rpm 14cm fans sweat.gif

Am afaird will fry this ram cos my old DDR3 ocz ram run very warm even with stock voltage sweat.gif
planning to clock higher and run 24/7 whistling.gif

for daily usage, i think it is pointless to run at higher speed with vdimm out of optimal range..
ur last time ocz is bought when? the only ramchip that i know runs hot is microns... for some ics
i dont think ur eco can get fried even with 1.75v with passive cooling..
*
Well i plan to run this ram at higher speed but within 1.65v sweat.gif
1705mhz with 8-8-8 still not stable @ 1.65v, prime blend failed within 10 minutes and pc hang lol,
without good oc skill + good imc, its just a dream doh.gif
just reverted to my old optimal setting sweat.gif

My old ram is fatality ddr3, at standard vdimm it run hotter than ripjaws i think.
Bleh unless i switch to watercooling, or change the hsf to Thermalright HR-02, there is no way to cool my ram shakehead.gif

about fatality, i donno, but last time , ocz have higher tendency to get microns inside..so perhaps u got a microns that some of em runs hot
ur eco not a microns or hyper..make the trcd loose abit.. im sure u can run it with 7-9-7 w/o problem..
try playing with ur vIMC alot.. they improves ram mileage..
*
Okay, will try that on next boot.

vIMC is that "CPU-NB VID"? how much should i add? after added 8GB of eco im stuck on 3.7GHz, cant go higher cause unstable. sweat.gif
previously was able to run at 3.9GHz and 3GHz NB without sweat when using Gskill ripjaw (this ram now fall into ah_khoo's hand already tongue.gif )
im suspecting my ram's timing too thigh...

btw 3GHz NB clock need how to add how much NB voltage? its weird because previously can run 3GHz NB without bumping the nb volt rclxub.gif

Do keep in mind that the 3GHz NB u referring is actually the CPU-NB, when u use ur ram slot to the fullest u may have to bump the cpu-nb a bit.. Try maybe bump the cup-nb volt to 1.2v ker.. hmm.gif
*
Im actually tried 1.3 but freeze when running prime95 blend, tried 1.35 was a no go either. going to try higher, previously 1.3v already stable enough sweat.gif
Now the question is, whats the "NB voltage" for?
