Kingston HyperX Ram?

I just had a bsod while benching while overclocked, prompted me to run the windows memory diagnostic which i had not before. While it passes any number of passes under the basic test it fails standard and extended on the first pass (10% in on standard).

Either the ram was okay but not great from the get go or ive damaged it.

Unfortunatly 8GB kits seem very expensive but replacing the 4GB i have now is pretty cheap. Saw DDR2 800 CL5 kits for 50 bucks on newegg. I bought kingston for my last laptop from them. Just wondering if I should be aiming for the lower latency and does this hyper X crap any better then their standard stuff? I will continue to overclock in situations such as GTA 4.

 

Lower latency RAM isnt worth the money but if your looking for performance at any cost, go ahead.

Have you run memtest 86+ ?

 

Nah I will give it a shot it looked like the CL5 and CL6 variety of that ram was the same price so.

 

I was about to make a new thread about this, but is there any laptop memory better then ddr2-800 @ 5-5-5-15 (excluding ddr3)?

 

Not that the latency is really worth paying more for...but I don't think so.

 

also, unless your laptop bios lets you adjust your timings (99.99% don't) it's likely going to default to 7-7-7-20

 

Depends on how you define better. In theory (benchmarks), there is DDR2-800 at CL4 but in real life, performance is identical to DDR2-800 CL5/CL6, and DDR2-533/DDR2-667, and even DDR3-1067/DDR3-1333...

 

Best what I've seen DDR2 800 are these :
Think I'll buy them ..

If you don't even utilize all of 4GB, then 8GB is just a waste of money.

 

if showing 4063 total ?

 

Alright i ran the memtest86+ and it passed. I wonder what the windows memory diag was getting problems from. The one in the boot loader is no where near as good as the one microsoft used to give out as an iso.

Guess I wont worry for now, rather not change it till 8GB kits get under 100.

 

You need to let memtest run for hours btw,

 

Yeah well 1 pass was nearly an hour i cant spare my main machine for that long lol. The machine runs fine under all normal circumstances. Besides it took 3 seconds for the built in to declare there is some sort of issue that it wishes to tell you nothing about.

Im more now wondering if i can find some ram that will overclock better. I am thinking my real limitation is the voltage and that the HyperX wont do much if at all better then whats in here.

 

If you are going to overclock it then try to use a higher rated RAM, like a 1066mhz PC2-8500 (not sure if they made it for notebooks though)

 

Yeah i was looking into that and didnt see any for laptop. Would be neat if they had. The chipset says it only supports up to DDR 2 800 but had there been 1066 for laptops one would hope it would run at the 800mhz speed and then have all that room for overclocking.

 

Oh i see, i guess they didnt bother making it for notebooks.

But yeah it probably wont give you all that extra room because it will be your chipset that will limit the OC. Having a higher rated RAM just means your RAM wont crap itself when overclocked.

 

Yeah assuming the ram or something else is the current hold back then the T9600 sitting next to me will clock to 3.2Ghz and is much needed for playing GTA4.... im mad i bought it sorta wish i could just sell it lol.

On the daily i dont need to overclock something like the T9600 it should have enough out of the box performance but it became clear that I now have one game that needs a alot more and i will be able to give it a little.

 

Do you OC through the bios or through Windows programs?

 

About the only thing u can do in the bios is make the hard drives near permanently not show up anymore. SetFSB.

 

Neat, don't think it would work for me (didn't see the pm45 chipset listed)

You need your clock generator what machine do you have? My G50 uses ICS9LPR604AGLF but plenty of other PM45's use other PLL's.

 

i have the hp dv4t. Not really made for oc, but I would love to try

 

Run your memtest86+ again overnight. I'd even do one stick at a time. I have Kingston HyperX 4-4-4-12 as you do, and I haven't had any problems at all. Try one stick at a time overnight.

On a side note there was zero performance improvement in any benchmarks with the lower latency RAM, whether synthetic or real world. I think the i965 controller isn't that efficient. Because I tried the same RAM in a GM45 Montevina at the same speed and timing and BAM i got more than a 15% increase in performance. Intel really reworked a good memory controlller in the Montevina (jealous.....)

 

Oh i didnt get that ram yet I have the stock stuff in here. Unless theres something thats deadly wrong with it i wont swap it for the same size.

WHen i get a chance I will run the memtest for 8 hours unless im up all night then itll have time for 2 lol.

 

Those HyperX chips are really good chips though, so I wouldn't expect you to have any problems with them. Good luck!!
