Compaq Presario V2000Z Memory Conspiracy!!

Remove the stick of 256 and throw it away or ebay it.

As long as your gig stick is 3200/400 it will boost your speed.

 

Laptop comes with 256 DDR333 memory(not DDR400) it will run at DDR333 speed, but if you take out that 256MB stick,1GB DDR400 will run at full DDR400 speed( mean 200Mhz). Keeping that 256MB DDR333 forces it all memory sticks at DDR333 speed

 

Correct!

It isn’t brain science people!

 

So 1.0G at DDR400 spped is generally/always better than 1.25G at DDR333 speed? Sorry, sometimes I am a little slow.

 

Yes, that is right( atleast as per my experience) and you could sell that 256 to some other poor soul( I did).

 

Depends. But my choice would be the faster ram. Remember that the ram is also used for video memory. So faster system ram = faster video ram. Its a double whammy.

 

It will not run at 200. It is going to run at 166 because that is all the bios will alow.

 

How about you only open up your trap if you have a Compaq V2000?

Tell that story to my computer as well as the other 4-5 people on the board that use DDR400 in their V2000.

CPUZ doesnt lie you troll.

 

V2000z does support ddr400 (200mhz), that's clear and I don't thing there's need to explain it anymore.
Yet, can anyone make it a little clearer what T1 and T2 timings are? V2000z series comes with default T2 timing and some people earlier in the thread said that T1 timings is much better.

I have version F.21 of the bios in mine. Will that make a difference?

 

Wow, you have the latest!
I am sure it should support DDR400. But I am wondering what else improvements it has over the bios I have F.13.

If you could post your ROM file it would be useful!!

 

How do I do that?

 

Where do I get the new bios? It is not on the v2000z download page. Thanks.

 

I have a RS428 chipset, you have a RS480. That i most likly the cause for the diffrent bios. Heck the model number isnt even the same

Mr. Hollywood mind telling us your entire notebook specs?

 

V2000z
Turion 64 1.8GHZ 512K cache
256 Ram
ATI 200M no productivity ports
Broadcom 54g
40GB HDD
Brightview
8X DVD
6 cell battery

 

I think even Mother board model is different, probably new revised MB(some improvement, I hope!!).
As per chipset, both are same expect one is 130nm process(RS480) vs 110nm(RS482). May be they have shortage for RS482 because of lot demand for this model( lot of Desktop boards are use this chip).

But I doubt if bios is different because of it. May be they will post this version later.

Here is info from Anandtech about these two

" The RS480 and the RS482 are the same chipset, with the RS482 having undergone a die shrink. We believed that the Grouper was still equipped with the RS480 chipset, when in fact, the Reference Board had the .11 process RS482 when we checked under the heatsink.

Whether RS482 or RS480, the performance should be essentially the same according to ATI. The RS480 is built on a .13 micron process, and the RS482 is a die-shrink to .11 micron. The chipsets are otherwise identical, except that ATI did make the move to a flip chip design in RS482. Whether it is a RS480 core or RS482 core, ATI calls the chipset Radeon Xpress 200. You will never hear ATI refer to the RS482 or RS480 in official documents, but we find the internal names to be useful for explaining what has and hasn't changed in the chipsets."

 

Chinna what is your chipset? I have the RS480, bios F.11 (well I will flash it these days)
My model is 3093, 47.OD. uff it gets complicated. What is this 47.OD?

 

Thanks, and sorry for the deleted post (I was on the previos page when I wrote mine)
Going for the new Bios then

 

482 = productivity ports
480 = no productivity ports

They use a different bios because for the 482 to support the productivity.

That’s my guess. It’s just faster that way to give different models different a bios rather that tweaking each bios individually based on the customers needs. They just send out 2 different pro configured bios.

 

I have RS482 and have the F.13 BIOS.

Wow! You are jumping to conclusions pretty fast!! It is same bios for all the versions. If you see the previous public release of bios, it is common for all CTO V2000z model irrespective of whether it has Productivity ports are not. But, it is quite possible(most likely) there are using different MB models(based on same chipset) with and without prodctivity ports. (like for Ex: ASUS P4P800 and P4P800E deluxe, all use same bios though they have some extra chipsets and features).

And as I explained in my previous post there is no difference in those chipsets other than manufacturing process and productivity ports has nothing to do with chipset as those are provided by completely different chipset. Probably, if you have idea about MB bios you will understand it.

And please do not jump to conclusions as it confuses newbies.

 

So is my computer not as good since the manufacturing process is bigger? Should I send it back and tell them I want the 110 version?

 

Don't think there's any difference... Typically, they just switch to smaller manufacturing process to save money... since they can pack more of the chip on the same silicon wafer.

This means they can produce more of the chips at the same cost to them. or they could to pass the savings by selling the chips cheaper.

 

Mine has productivity ports (l2000 does not come without them). There should not be any difference between l2000 and v2000z in the MB version, I think.
I wonder, why some people have the same model MB and different chipset... anyways, I think we are going too much into this stuff as there is no difference whatsoever in performance (so far )

 

You are absolutely right. This is not even worth discussing in detail as we know these two are essentially same chipset. And it is same bios for all V2000z/L2000 models. Probably just installing available chip.

 

I just ordered a custom V2000Z w/ the Sempron 3300+ (2.0GHz/128k) and a single 256Mb stick.

questions:
1. Is there any performance benefit to running matched pairs ie 2x512Mb PC3200 over a single 1024Mb PC3200 stick?

2. Any documented problems yet w/ running 2x1024Mb PC3200?

Also curious if anyone has a link to some benchmarks on the Mobile 3300+.

Thanks

 

Current AMD notebook CPUs are single-channel, so there's no advantage to running matched pairs of SODIMMs. Get the single 1GB PC3200 stick. Stick with the better brands, AMD's high-performance integrated memory controller isn't as tolerant of mediocrity as Intel's external controllers. Crucial is my favorite, others have spoken highly of OCZ.

 

I've got the OCZ DDR400 1GB stick, detects fine, runs fine. (looped windows memtest, fully stable at 2.5-4-4, but unable to run at 1T timing through A64 Tweaker)

Can't do anymore test, upgraded from the V2305 to the V4000T

 

Hello guys

I have got Twinmos 1024MB DDR400 with label DDR400 (CL2.5) but it runs as CL3.0 in my V2000Z

is it next wrongly listed stick or
there is no posibility to run any (other than OCZ as above ) stick as CL2,5

 

I guess the only way to find out is to check the memory on another computer. After all, it might be that v2000z's Bios messes up the memory, although I can't understand how OCZ would get through in this case.
You can try to tweak the memory settings but as far as I know, there is no way to keep the new settings after standby/restart.

 

checking the memory in another V2000Z or L2000 will be a problem i don't know anybody with this notebooks
but I'll check it on ACER 5024
