Mission impossible : 290 1:1 2x512MB Hynix –D5 CMD 1T @ DFI

When received my new Board (DFI LanParty UT NF3 250GB) and install it I was very impressed with the overall overclocking potential….
Was possible to run my ADATA VITESTA DDR500 with Hynix –D5 chips at 265 FSB @ 2x512MB 1:1 at default timing settings at CMD 1T.
When used 1x512MB was possible to run 290 1:1 again with CMD 1T..
But 290MHZ FSB 1:1 with ONLY 1X512MB was a big problem for gaming Performance and that was hurt a lot…

Last night I starting to spend a lot of time to playing with DDR timing settings included on BIOS….
After 5 Hours of searching and testing finally mission completed .
Now running a Perfect 285 FBS 1:1 @ CL 3.5 4-4-6 1T @ 3.08 VDDR rock stable error free on MEMTEST+ @ PRIME95 @ Super PI 32MB @ Games….

When Raising FSB up to 290 Getting 121 errors per loop on 5th test of MEMTEST+ and need to play a little more to get it error free….

Please note that I have an A64 3200+ Claw C0 1mb Cache 1 year old which means that is a BAD overclocker versus to new A64 stepping …

Need a little more tweak to raise bandwidth and FSB before I post all the DDR timings here…

Now enjoy with me some screens and just wait for the timings…..

Here is SANDRA MEM...

Just compare same FSB at 1x512MB @ auto DDR Settings....
As you see i dont loose much :D

And here is A64 Tweaker screen reporting CL4 but i choose CL3.5 on BIOS

What time do you get in Superpi 1M ?

At 277 X 9 = 2493 i get 35sec

My last SPI 1MB at 278 X 9 = 2507MHZ @ 1x512MB @ auto timming settings was....

But i not completed all the tests yet....
I will compare also the 3D Performance to see +/- i get....

I'm at work now after a long long night and i don't have with me more Bench to show...

Stay tunned ... I'll BE BACK.... :D

Next step is to maximize FSB with 1X512MB and lets hope 310MHz - DDR620 @ CMD 1T can be stable.. :rolleyes: :D

Great Job Dagalidis ! Hope you get 300 1:1 :)

Καλό το Dfi τελικά Μήτσο ε ?:)

Thanks my friend....

Greeklish : Αστέρι φίλε - πραγαματικό διαμάντι. :D End Greeklish

Nice Dagalidis, now all you have to get is a nice clocking 3700+ and you can probuably get 31/32 sec on SPI maybe even 30 if you push it real hard.

Congratulation on the oc! 290MHz is quite impossible for Hynix but you did it, though the timing is a little lousy...

What's the difference between the fastest at 2.5-3-3 1T vs 3.5-4-4?

Thanks....

I cant say for sure about the difference in Performance cause never used 2.5-3-3- 1T....
But i will drop the fsb to get stable 2.5-3-3 1T and compare 3D VS 3.5-4-4 1T at same FSB-CPU MHz and see...
I believe 1 - 2 % is the max drop in performance .... but on the other hand this drop is reversible due to fact of high FSB gain at same cpu mhz.... :D

I for myself stick to 2x512MB Hynix D43 at 26XMhz 2.5-3-3 1T on my Lanparty. My 3200+ CG 1M max out at around 2600-2630MHz so I just let it run at 1:1 262x10. Wonder if it'd do 290 x 9 1:1 at 3.5-4-4 and any faster...

Dagalidis, is this true of what I am reading in this review this board can do 2.108vcore? (1.55 basevoltage x 136%) If thats the case Im getting this board and 3.1vdimm and 1.9cset voltage. Sounds like a really spectacular board.

Its true my friend both of your readings... :D
Also you can have up to 4.0 VMEM using modded BIOS @ PSU with 3.3Volts rail adjustable up to 4.2 Volts... :D

wow..... wow wow wow....

2 512mb sticks at almost 300 on a 754 is impressive! and at 1t? :eek:

Here is my OCZ PC4000 Gold rev2 (Hynix D5):

FSB300 Cas 3-3-3 2T (1 stick 512 with DDR booster):

http://usuarios.lycos.es/krampak/Ben...0_3-3-3_2T.JPG

FSB280 Cas 2'5-3-3 1T (2 sticks 512 without DDR Booster):

http://usuarios.lycos.es/krampak/Ben...9;5-3-3_1T.JPG

I got it up to 305 2'5-3-3 2T but didn't finalyze the test :P And my max a 1T was 285 2'5-3-3 with 3'2V. Don't tried more Voltage yet (the mobo is stoping me, with a divider 200:180 it freezes at more than 310Mhz).

PD: DFI lan party everything air cooled. (yea the second one has a good cpu temp, it was outside of my house @ 7ºC ambient :banana: )

2 x 512mb isn't realy holding me back here:

http://home.scarlet.be/~patrboon/10.JPG

This with 1T, 2 x 512 Ocz pc3200 rev2 and a Lanparty Ut.

Rabbi is that real??? or are you using a half multi? Can you do some benches for us.

Off course those settings are not stable, but it was only to show that 2x512mb isn't a bottleneck.


Here a bandwith shot:
http://home.scarlet.be/~patrboon/roger%20that.JPG
Cpu-Z shows only 512, but this was with 2x512. I can run it again if needed.

This is quite stable:

http://home.scarlet.be/~patrboon/9.JPG

This is with mp 7, for some reason my motherboard won't post with mp 8 htt 300.

Run SuperPI and try =)

Ok, will try that tomorow.

Ok my friends...

Here is some specs of my system

CPU = 3200+ Claw C0 1mb Cache
DDR = Adata Vitesta DDR500 (Hynix -D5) 2x512MB
Mobo = DFI LanParty UT NF3 250GB
PSU = Antec True Power 480W
Cpu Watercooled by EXOS

LTD = x2.5 For FSB > 300Mhz
x3 For FSB < 300

Those are timmings used for 295 2x512MB @ 1T...

Dram Frequency Set(Mhz) = 200(Mhz)(1/01)
Command Per Clock(CPC) = Enable(1T)
Cas Latency Control(tCL) = 3.5
RAS# to CAS# delay(tRCD) = 4
Min RAS# active timing(tRAS) = 06
Row Precharge timing(tRP) = 4
Row Cycle Time(tRC) = 11
Row Refresh cyc time(tRFC) = 17
Row to Row Delay(also called Ras to Ras delay)(tRRD) = 0
Write Recovery Time(tWR) = 2
Write to read Delay(tWTR) = 1
Read to Write delay(tRTW) = 5
Refresh Period(tREF) = 3632
DQS skew Control = Increase Skew
DQS Skew Value = 16 or 32 (i use 32)
DRAM Drive Strength = Level 1
Max Asynce lantency = 8
Read Preamble time = 5.5nano sec
Idle Cycle Limit = 0 or 16 (i use 0)
Dynamic Counter = Enable
R/W Queue Bypass = 8x
Bypass Max = 5x
32 byte Granulation= Disable (8burst)

Until now i manage to have 295 1:1 @ 2x512MB 1T error free on MEMTEST but 287 stable on Windows

Also using same timings using 1x512MB @1T i have 315 error free on MEMTEST+ but again ONLY 290 stable on windows....

I know its not a RAM issue but probably CPU limit for my old Claw C0 3200+ 1MB cache..
My cpu was of one the first step and is 1 year old..
So is a bad overclocker and suffer from Mem Controller instability...
I cant explain for sure why i can pass 2,5 hours wall time of 5th MEMTEST using 312 Mhz - DDR624 and when i boot into windows and try to bench using Super PI - FAST PI or a heavy 3D Bench, i get random black screens and Restart...

I will try finding out why get those problems and will inform you...

Thanks for posting settings, always good with new ideas!
And might solve some clocking for other that have CO cpu.

@Dagalids

I see you have a C0 ClawHammer. What is the highest stable overclock you have reached with that CPU? I can't seem to get mine high with any memory settings. I think mine is just a crappy CPU:(

SuperPi @ 2100mhz:

http://home.scarlet.be/~patrboon/superpi%202100.JPG

Dagalidis, great job as always my friend! :up:

C0 ClawHammers seem to have bad memory controllers.
I get errors in test 6 above 290 which i think are CPU related, test 5 passes np even at DDR600 2,5-3-3-8.
I hope to test a new CPU soon.

Rabbi, nice to see you here (OC4ever @ GoT right?) you have some very nice RAM and CPU!!
Great OC. ;)

at 290 you get errors but at 300 you do not?
