Changing L2 Cache Size...

By cyberghost_1 ·
Hello again... I'm using a Compaq Mini Netbook CQ10-120LA...Win7 Ultimate x86, Atom N270 @ 1.60GHz, 160GB SATA-II HDD and now 2GB DDR2-800 PC2-6400 RAM. My Q is: What are the effects of changing my L2 Cache from 256k to 512k?? The thing is that CPU-Z (CPUID) and Everest Ultimate tell me that my L2 Cache is 512k...BUT Windows 7 Manager tells me that its actually at 256k... Truthfully I'm confused... What's better as far as performance is concerned?? 256k or 512k?? I honestly don't know much about what the L2 Cache does and its purpose... Please help me out guys I would really appreciate any and all info concerning this... THX...

Turns out, the thing has to be implemented at every level, by hand... shouldn't take but a couple of millennia.

Benchmark Apps or Tools...

by cyberghost_1 In reply to You assume wrong.

What Benchmark software would u recommend?? I have Everest Ultimate... would that be sufficient?? Or is there better SW out there?? I benchmarked using Everest and my results were about the same but I still performed less than an Atom 230 HT with the same Chipset and RAM clock speeds.. but only on 4 of the 6 tests I performed...any tips...

L2 Cache is effectively Volatile Memory

by OH Smeg Moderator In reply to Changing L2 Cache Size...

That is written to in an attempt to speed up actions. This can be in the CPU for instance and acts to give a constant uninterrupted stream of Data for CPU intensive processes.

Buy just the same it can also be referring to the Cache on a HDD which does the same thing but in the case of the CPU it tries to minimize Read Write Operations Lags from the HDD.

Here though I would think that this is referring to the CPU which supports Hyper Threading so it accepts 2 Streams of Data and has 256K of L2 Cache per Data Stream hence the 2 X 256 = 512.

You can not change this figure as it is part of the CPU and is to do with the way that the CPU works.

As you have been told previously these Netbooks where never designed to run a OS as intensive as 7 and the hardware is not up to the job that you are giving it.

Max out the amount of RAM it is possible to install and that is about the best that things will ever get here.

Atom N270 info . . .

by Who Am I Really In reply to Changing L2 Cache Size...

Here's what Intel says about the processor:

http://ark.intel.com/Product.aspx?id=36331

I'm guessing that you have it in HT mode
and as Oh Smeg already mentioned

- in HT mode yer 512K Cache will be split and shared between the 2 logical processors an only appear to winders as 256K

Aye - this isn't like the XP install misconfiguration.

by seanferd In reply to Atom N270 info . . .

The cache is split between two cores, since HT makes one core "look like" two.

XP did, however, like to short you L2 cache, which was fixable wit a registry edit.
