shep48 May 10, 2005 Share shep48 Member May 10, 2005 added a 2nd pair of 512 sticks and got 20 fps less in video stress test. right clicked on comp, it shows 2 gig of ram. i have 4 sticks of this here any ideas?? Link to comment Share on other sites More sharing options...
Unclean May 10, 2005 Share Unclean Member May 10, 2005 Take out the RAM! ...that reminds me of a patient that tells the doctor "it hurts when I move my arm like this!" and the doctor replies "well, stop doing that then!" Seriously though, what type of RAM did you have prior to the installation? The same as what's in the link? If you have four sticks of the same exact RAM (checking the stickers on the RAM, not the box/packaging), post up the information about your MOBO, system resources (utilization) before/after, etc. Link to comment Share on other sites More sharing options...
shep48 May 10, 2005 Author Share shep48 Member May 10, 2005 i had 2 of those and just added 2 more all the same Link to comment Share on other sites More sharing options...
whudats May 10, 2005 Share whudats Member May 10, 2005 I am no kind of computer expert, and I am not meaning to insult your computer ability, but do the bus speeds or whatever they are match? I mean the new RAM and your old RAM or the RAM and your MB? I'm not sure, but if you are using two different kinds of RAM I think it can cause issues. BUT, I wouldn't think that it would affect your FPS...unless it's simultaneously trying to pull info from the two different types of RAM you have installed...?

shep48 May 10, 2005 Author Share shep48 Member May 10, 2005 ok listen all 4 sticks are the exact same.... i just went back to 2 sticks and jumped up 20fps how is this possible? my motherb is dfi lanparty nf4 sli-dr and yes its supports dual channels Link to comment Share on other sites More sharing options...
Unclean May 10, 2005 Share Unclean Member May 10, 2005 (edited) Whudats, shep mentioned that the RAM was the same (but you may not have seen it b/c you were composing a reply). Well, I did do tech support professionally for a little over 3 years, so here are the troubleshooting steps I would perform: 1. Just for kicks, compare the labels on the old and new RAM. They should match. If not, maybe the RAM was mis-packaged. 2. Take out the new ram, test your FPS. 3. Swap out the old RAM with the new RAM, test your FPS. If the FPS is the same with new/old RAM, then it's most likely a mobo issue (setting? hardware limitation?). However, if there is a difference between the new and old, well, you know it's the RAM. Edit: just saw your last post. Skip step 2. Edited May 10, 2005 by Unclean Link to comment Share on other sites More sharing options...
shep48 May 10, 2005 Author Share shep48 Member May 10, 2005 ok either pair are 20 fps higher than all together i tried all combinations and same thing.... Link to comment Share on other sites More sharing options...
mongoloido May 10, 2005 Share mongoloido Member May 10, 2005 I don't understand any of this, but I'm sure I read something about this situation. At least with AMD, you want two sticks, not four, in order to get the best performance. For whatever reason, the bus speeds or something go down when there are four slots used. You really want 2 sticks of 1gig... I know I didn't explain that well, but maybe it will help you google the good answer. Link to comment Share on other sites More sharing options...

Preacher May 10, 2005 Share Preacher Member May 10, 2005 Well it only supports one set of duel channel ram, that is why it lowers your fps. It is using all the Ram on single channels Link to comment Share on other sites More sharing options...
Guest zerodamage May 10, 2005 Share Guest zerodamage Guests May 10, 2005 The issue is more than likely timing of the memory sticks. You have CAS latency and etc and adding more than 2 sticks slows these values down. You also have to consider that Windows now has to address 2G of RAM and that can add to the lower performance.

shep48 May 10, 2005 Author Share shep48 Member May 10, 2005 heres what DFI says Entirely possible you saw those results as inserting 4 sticks means the 2T command is enabled as per AMD specs instead of 1T and most boards will not run the 2T CPC with 4 sticks. In fact AMD is hyping thier newer "E" stepping cpus to try and work around that problem. But for general use I find the larger ram to be a benfit and you cannot with your eyes see 20fps.

Preacher May 11, 2005 Share Preacher Member May 11, 2005 that ram should eliminate the problem and give you an increase in your fps. Also if you want to sell your old RAM PM me, as I'm in the market. Link to comment Share on other sites More sharing options...
shep48 May 11, 2005 Author Share shep48 Member May 11, 2005 well clue gets firsts, but if he doesnt want it your up next. the price on newegg is 129 i have a 19.65 restock fee so if u or any one is interested $110 here it is the link,here must know soon , I want to move on Link to comment Share on other sites More sharing options...

Guest zerodamage May 11, 2005 Share Guest zerodamage Guests May 11, 2005 I was just reading that using Dual Channel in some of the newer boards with 4 sticks drops the bus to 333 from 400. This may be what happened to you. Link to comment Share on other sites More sharing options...

This may be what happened to you. <{POST_SNAPBACK}> dual channel on an amd64 machine will run at 333 instead of 400, and at 2t command processing. you are right in returning the ram. for future knowlege the new dual cores should have it fixxed Link to comment Share on other sites More sharing options...
NOFX May 12, 2005 Share NOFX Member May 12, 2005 what about dual channel on a P4 board. I have 4 sticks of 256. I wonder if I take 256 out I will see more FPS increase Link to comment Share on other sites More sharing options...
Cujo May 12, 2005 Share Cujo Member May 12, 2005 what about dual channel on a P4 board. I have 4 sticks of 256. I wonder if I take 256 out I will see more FPS increase <{POST_SNAPBACK}> intel has a completely different memory controller. 4 sticks should work just fine. also, if you take only 256mb out then you will no longer be using dual channel i believe... as per the original topic. you will notice NO DIFFERNCE going from 1 gig to 2 gig as at this point source doesn't even utilize 1gig of ram! the only time you will notice a difference is when you're using enough ram at one time that pagefiling is necessary... maybe if you do heavy photoshopping then it might be necessary. since my last reboot (3 days ago), my peak ram usage is only ~674mb. i have played source in that time. you can check this in your windows taskmanager under the performance tab and look in the bottom left corner. it says commit charge and then peak underneath. that number is the MOST amount of ram your system has addressed since your last reboot. if you're looking for a performance increase then post your full system specs and i'll be able to advise you on your best upgrade solution.
