Timing for Kingston Valueram

[jhaveri]

What I thought was stable 3.5 GHZ system was not stable after all, see the link below.


Help with overclocking - Kingston 8 GB valueram system

Windows 7 was freezing at random times. But Prime95 was stable for 8 hours. So I decided to run memtest86+ for several hours (5 passes) and I got few errors. So it is my 8 GB (4 2GB sicks) Kingston ValueRam. The stock timings are 9 9 9 24 33. In Bios they are under SPD tab. Actually the timing under AUTO are lot less 7 7 7 20 or so.

So I did few tests. Memtest 86+ gives no errors for 5 passes if reduce the FSB to 240 i.e. 3.36 MHZ CPU speed. If I go up to FSB 250 i.e. 3.50 MHz CPU speed, memtest86+ gives errors in 8 minutes, at pass 1, test 5.

I tried to relax the timing but not very successful. In BIOS, under manual adjustments of memory timing, there are many numbers. Their default SPD values are: (9 9 9 24 2T 5 10 5 33 4). But CPU-Z under memory tab shows only 5 of them (9 9 9 24 33). So I have been relaxing them only leaving others at their default values. So far I tried

9 10 9 25 35
9 10 9 26 36
9 10 10 25 35
9 10 10 26 36

But they all give errors in memtest86+ at test5 pass 1

Any hope for getting Kingston stable memory for 3.5 GHZ? What are the timings I should try?

Thanks, -jhaveri

Try prime95 on blend for ram, and did you set your voltage manually?

Yes, I did set voltage manually. I am running blend on Prime95. I get BSOD after about 45 minutes.

Download cpuz, what is it saying for memory and cpu

Download cpuz, what is it saying for memory and cpu

I am wondering if my system has other issues. For example, I had a stable 3.2 GHz system with timing 8 8 8 22 30 which ran for 3 hours on Prime95 before I stopped Prime95. I ran that today and it gave BSOD in 45 minutes.

So currently I am testing default BIOS setting on Prime95, 2.8 GHZ CPU with 200 FSB and memory at 1333 MHz with 9 9 9 20 34 timing. Here are the screenshots from CPUZ and HWMonitor.

If this runs on Prime95 for 1 to 2 hour, I will overclock it once again to FSB 235. In that case, what would you recommend I try for memory settings?

Thanks.

I'm assuming you think that to overclock your processor you have to overclock your ram. You don't. Keep your ram at stock settings (1333mhz)

I actually reduced RAM multiplier from 6.66 default to 5.33 when I overclock CPU to 235 FSB. Thus 235*5.33=1252 MHz, less than but close to 1333 MHz. If I had left default 6.66, I would have overclocked RAM to 1565 MHz.

I running Prime95 now on overclocked CPU. Here are screenshots.

See how long this runs stable.

All voltages are at stock values except CPU-NB

DRAM 1.5v
NB 1.1 v
vcore 1.4v
CPU-NB 1.225 v

Any suggestion for next step if this also gives BSOD. It has been only running for 13 minutes.

 

[jhaveri]

Why is your dram at 1.5v, isn't it 1.8v ram?

The Kingston Valueram is rated 1.5 v .

Prime95 once again BSOD after 30 minutes.

 

[geekapproved]

I would try changing the dram to 1.4v and 1.6v and see if you can get that stable.

I am running with 1.56 volts now, to be on the safe side. I read here that 1.6 should be the abs max for this CPU.

 

[geekapproved]

I said DRAM, not CPU.

 

[jhaveri]

I said DRAM, not CPU.

Yes, it is DRAM at 1.56 volts, CPU is stil at 1.4, CPU-NB at 1.25, and NB at 1.16 (+.06)

Your RAM need Heatsink jacket and Always memtes86+ sometimes,
u can see JEDEC your RAM : 3:10/667 = 9-9-9-24-30 same 3:8/533= 8-8-8-20-27 / 400 =6-6-6-15-20 (all same Speed)

here list of OC RAM value :
Standard 1333 : FSB 200 vdim default from mobo (156~157) i have it !

1333 : 9-9-9-24-30 , raise FSB 255 get 850(CPU-Z) over volt vdim 1.60 = 1.56 default + OV 0.015 get 3.57Ghz Vcore:1.344 CPU NB-auto HT link (2000) get 2500

1066 : 8-9-9-25-41 (DC0 /both), raise FSB 286 get 745 (CPU-Z) vdim over volt 1.63 (it's Max voltage for RAm value) 4.004 Ghz Vcore:1.52 CPU-NB : 0.025
HT link 1400 get 2000 (CPU-Z)
(in 4Ghz always Check Max temperature )

800 : 6-7-7-20-35 raise FSB 300 get 600(CPU-Z) vdim over volt 1.63 (it's Max voltage for RAM value) Clock CPU 4.177 ghz
(be carefull with Temperature)

good luck !

Thanks henydiah, as usual, you are lifesaver. I have taken your advice and got almost there.

Since I do not have ram heatsink, I am using your last RAM settings, i.e.
800: with 6-7-7-20- 27 timing rather than 6-7-7-20-35, because the last number in my CPUZ is (27) and not (35) see below.

I also use FSB to 265 to keep temps below 60 degree since my CPU cooler Thermatlake SpinQ is OK not great.

My CPU is now 3710 MHz, NB 2385 MZ, HT 2120 MHz,
vcore 1.4 volts
CPU-NB 1.25 volts (+.075 v)
vdimm is default at 1.5 v
NB is default at 1.1 v.

Prime95 was stable for 3 hours no errors. I stopped it since HW Monitor got frozen and I got nervous about the CPU temps. But the rest of the system was stable.

After killing Prime95, I ran Inel Burn Test. I could run 10 standard tests with no problems, but I could not run with high settings, it would give blue screen of death (BSOD).

So my questions:

1) should I change the 4th timing to 35 rather than 27 i.i. (6-7-7-35) and not 6-7-7-27 ?

2) Is my current system stable? Prime95 was stable for 3 hours. Intel Burn test was stable in standard settings for 10 tests but NOT in high setting.

3) If my system is unstable, which volts should I increase?
vcore to 1.425?
CPU-NB to 1.275 or even 1.3 v?
vdimm is now at 1.5. Shiuld I go to 1.6 v? max for Kingston?
what about NB volts? Does that need to be changed?

Appreciate all your help. Looks like I may already be there? Not quite sure though.

If your system is unstable, don't increase any volts! Decrease overclock. If you can't pass 24hrs of Prime95, your system is not stable.

I don't understand why you would even attempt such a ridiculous oveclock with Value Ram and a cheap cpu cooler. Makes no sense to me. You have to address the issues before they cause problems, not after.

I think my system instability seems to be from memory timing rather than volts, based on several timing adjustments and checking with memtest86+.

I got Kingston as a part of package deal on new system from Newegg (poor planning on my part, should have checked posts before ordering). Anyway, I am stuck with it for a while. I have gone through a lot of posts regarding valueram and agree with you that it is not great for overclocking. However, people have successfully overclocked valueram, key is not to exceed rated speed of 1333 MHz and volts above 1.6. Hence I am actually decreasing the speed to 1000 MHz (multiplier 4 rather than 5.33 at FSB 250 or 265).

So I did go down to 3290 MHz (FSB 235), and have a stable overclock with Prime95 (8 hours) and Intelburn test (very high setting). Now testing 3500 MHz, and looks good so far, 2 hours on Prime95 and going.

By the way, Thermaltake SpinQ is not cheap, was $72 at Best Buy. I got it based on recommedation in this Forum. Is is better than the stock, but not great. I might actually return it before its 30 days are over and get Coolmaster 212+.

I know very difficult OC RAM Value, very very hard ! this is important to get Jacket Heatsink for RAM, it's very cheap $3 but I don't know where you can buy it ?.. prime95 Stress test run 8 hours maybe can make your RAM very very hot. in this case you don't Oc your RAM stay in default just Increase FSB from 235, remember step by step till get max to get Stable. this is maximum.
maybe next time u must upgrade your Extreme RAM, if u like kingstone get Hyper X. good luck

Thanks henydiah. Actually, I got pretty good stability even with FSB 250 (3500 MHz CPU) and underclocking RAM. It is at 1000 MHz. I don't plan to go above 3500 MHz CPU untill I find heat jaket for RAM.

I do appreciate your help. Regards, - jhaveri

That's what I suggested in my first post to you, that you don't need to overclock your ram to overclock your cpu, keep it at stock values. I guess you just didn't pay attention. I wouldn't overclock value ram, even with heatsinks, because it's lower binned memory that wont like running over its rated speed.
